Moreover, in small and fragmented populations that have low genetic diversity and experience inbreeding depression, hybridization can restore population viability [165,166]. . Inbreeding affects the rate of genetic improvement in several ways. As we get to know more about the human body, we can understand how to manage and cure various conditions. Inbreeding and brood stock management. The researchers found that inbreeding in humans causes physical and mental problems, though the severity of those effects was somewhat limited. Inbreeding is common, specifically, in the eastern part of Kentucky, and the region is plagued by the stereotype that every family is an inbred family. These are levels considered well above what would be safe for either humans or wild animal populations. Key Points. That is, the growth rate and mature weight would moderately decrease. Decisions about which animals need to be mated are often seen in relation toMirjana Baban. , restoration of genetic diversity and mitigation of inbreeding depression through gene flow can be a valuable tool in conservation of small, isolated. 25. For breeders, it is a useful way of fixing traits in a breed—the pedigrees of some exhibition dogs show that many of their forebears are closely related. The two dogs you are trying to breed shouldn’t share common ancestors at least 4 generations back. 6. 25. As a result, any seed stock producer is practicing some inbreeding. So. Inbreeding can preserve desirable traits, establish genetically pure lines, accelerate genetic improvement, and aid in scientific research. For breeders, it is a useful way of fixing traits in a breed—the pedigrees of some exhibition dogs show that many of their forebears are closely related. Homozygosity is a measure of the. The phenomenon of inbreeding depression was already documented in the 19th century by Charles Darwin, who studied 57 plant species and observed that the offspring of self-fertilized plants were shorter,. Advantages: i) Inbreeding is necessary to develop a pure line in an animal. Vigorous sexual reproduction can even lead to temporary amnesia, but it can also improve personal memory. In this paper, we propose five reasons. Thought of as bad by nearly everyone except the very experienced breeders who CAN and DO use it sucessfully. Research in the Boyko Lab has shown that a 10% increase in inbreeding can lead to a 6% reduction in adult size (poor growth) and a six- to ten-month reduction in lifespan. In a 1993 study, it was found that, in Australian beef cattle, a 1% increase in inbreeding resulted in an increase of one day in the calving interval, while 2% fewer calves were weaned on average. Inbreeding: mating between individuals with one or more com-mon ancestors. And in nature, when the pros of. The average for the seven traits that inbreeding negatively impacted in the study was between 0. Inbreeding may be close inbreeding or line breeding. Inbreeding is the mating of organisms closely related by ancestry. In the developed world, the average lifespan is approaching 85 years for top nations. progeny lifespan were all lower when progeny were the result of crosses with pollen taken close to a receptor plant. Other articles where linebreeding is discussed: inbreeding: Linebreeding is a form of inbreeding that involves selection of mates on the basis of their relationships to a certain superior ancestor. As they report in this issue of Current Biology, Harrisson et al. It is widely used in breeding domestic animals, both pet-stock and farm livestock. Unfortunately, most dog breeds hold high. It is the most risky of the inbreeding systems. Suggest Corrections. )inbreeding is likely, concern about outbreeding depres-sion should not prevent actions to alleviate inbreeding depression. 25. A study of cheetah skulls in museum collections showed that their skulls are relatively asymmetrical. Outbreeding, the reverse case of inbreeding, means production of offspring through mating between individuals unrelated or distantly related by ancestral descendent. Inbreeding is the mating of two close relatives. Question formulation. In a way it is like heterosis only in a purebred situation. The advantages of inbreeding may be the result of a tendency to preserve the structures of alleles interacting at different loci that have been adopted together by a common selective history. The inbreeding system involves the identification and selection of superior males and superior females, preferably from. - Outbreeding between populations with chromosomal incompatibilities or those adapted to different environmental conditions can also increase the risk of extinction. That encourages reproduction to occur so that the cycle of life can continue. - Continuous inbreeding within closely related species, eventually decreases fertility and productivity, and it is called - Inbreeding depression. inbreeding synonyms, inbreeding pronunciation, inbreeding translation, English dictionary definition of inbreeding.

Inbreeding depression refers to the decrease in mean phenotypic value with increased levels of inbreeding [1,2]. Animal breeding is one of the important aspects of animal husbandry. One of the main benefits of crossbreeding is that there is a reduction in inbreeding. 1371/journal. Inbreeding is defined as the mating of related individuals. inbreeding is asymmetrical skull development. Gene tests showed that birds with a high degree of inbreeding had shorter lives and reproduced more poorly than birds that were not as inbred. As the genetic architecture of common complex diseases of late onset is emerging through intensive research, it is intriguing to assess the predicted effect of inbreeding on those diseases. " With dominant traits, one can still see the expression of the traits and can remove those traits whether one outcrosses, line breeds or inbreeds. Therefore, we generally reserve the term inbreeding for the mating of animals that are more closely related than the average of the breed. When this happens, an organism is described as inbred or purebred. With recessive traits, outcrossing allows for the recessive traits. Inbreeding is technically defined as the mating of animals more closely related than the average relationship within the breed or population concerned. It is an art and a. These games contain scenes of incest that lead to impregnation. About 40 percent of the population marries a cousin in Egypt, according to a 2016 report in The Economist,. The inclusion criteria limited the analysis to explicit studies of mate choice, notes Regina Vega-Trejo, an evolutionary.

Breeding sibling dogs is a double-edged sword. While it is well established that inbreeding can increase a plant’s susceptibility to herbivores by diminishing morphological and chemical defences (Campbell et al. For these breeds, those slopes are about 0. Inbreeding depression has been observed to occur in wild animals with severe consequences [2,3]. Definition. It results in a decline in survival and reproduction (reproductive fitness), known as inbreeding depression, in most species of plants and animals. Definitions. Measurement of inbreeding in terms of the degree of consanguinity between two parents is another significant application of data on consanguinity. 2013. 2004 Dec;28 (2):943-50. Inbreeding: Harmful recessive alleles may be exposed during inbreeding. Inbreeding depression is a reduction in fitness in the offspring as a result of inbreeding. The men are tied up and brought before leader of the cannibals. In the broadest sense, all animals within a certain breed are somewhat related, but the term inbreeding refers to mating of individuals that are more closely related than the breed average – such as sire to daughter, half-siblings, sire to granddaughter, etc. This is. Inbreeding depression is the reduced survival and fertility of offspring of related individuals. In the 1880s and 1890s, writers such as Mary Noailles Murfree and John Fox Jr. The North Central regional dairy cattle-breeding project (involvingInbreeding, by virtue of its consequence on traits of interest, is a topic of major interest for geneticists and animal breeders. 25. This. Killer whales first reproduce at about 10 years old and reach their reproductive prime in their early twenties. Step 3. You can use these devices to keep birds away from your garden or your home as well. Moreover, in small and fragmented populations that have low genetic diversity and experience inbreeding depression, hybridization can restore population viability [165,166]. With the animals living in closer proximity, it’s often difficult to step in and stop inbreeding. After many generations of inbreeding, the offspring will be almost genetically identical, and will produce identical offspring. It provides a one-of-a-kind and uncomplicated. Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. Inbreeding is an act where two relative dogs mate with one another to produce offspring. Breeding systems serve to promote and preserve desired genetic traits in a breed or species. Vocabulary lists containing inbreeding. Inbreeding and pedigree construction. We explored the relationships between inbreeding, morphology and health using genotype based inbreeding estimates, body weight and insurance data for morbidity. Yes, Manusmriti forbids sexual intercourse with a virgin girl (without marriage). 25%. It occurs as a result of cross between two genetically different parents. Inbreeding within gymnosperms often occurs due to small populations. . If learning biology is in your DNA, you'll want. When you inbreed, cull heavily, only keeping what you are really. The application of this. , 2019) has set a new state-of-the-art performance on sentence-pair regression tasks like semantic textual similarity (STS). There are two basic causes of problems in inbred individuals: simple bad recessive genes which can be removed from the genepool, and the simple lack of diversity in the genes. Therefore, we generally reserve the term inbreeding for the mating of animals that are more closely related than the average of the breed. Disadvantages: I nbreeding depression is the reduction in the fertility and productivity of an organism due to continuous inbreeding. Disadvantages of Inbreeding: Inbreeding misery is the reduction in the fertility and productivity of an organism due to incessant inbreeding. Inbreeding, then, will tend to produce offspring who are more likely to. (Where, F 1 =first filial generation, F 2. Inbreeding depression is a reduction in fitness in the offspring as a result of inbreeding. For example, according to Rothschild, while inbreeding increases the risk of passing on faulty genes, it also ensures the preservation of good genes within a population. From the Home page, select the New Email icon to start a new message. of a particular hybrid organism over its parents. Based on meta-analysis conducted on 57 studies and seven livestock species considering a wide variety of selected traits, it was estimated that inbreeding depression corresponds to on average a decrease of 0. 007) (black dashed line) is the lowest level of recent inbreeding, which is like the average pedigree inbreeding of 0. Lu, in Brenner's Encyclopedia of Genetics (Second Edition), 2013 Abstract. In its simplest form, inbreeding depression occurs when relatives in a small group mate, which reduces the population's ability to persist and reproduce. Choose Adobe Acrobat Document from the Create New option, and then click OK. In humans, high levels of inbreeding (3-6%) have. Inbreeding Theory. Outbreeding devices refers to the processes or mechanisms that plants use to avoid self-pollination. Animal breeding is a branch of animal science that addresses the evaluation of the genetic value. Intense inbreeding might cause the producing stock to lose vigour. It can encourage the growth of brain cells. With the animals living in closer proximity, it’s often difficult to step in and stop inbreeding. e. : existing as a basic part of a person's nature or character. Scott is a certified genetic counselor and the Deputy Director of the Genetics and Public. [7] have performed an in-depth investigation into inbreeding depression in an endangered bird, and show that the costs of inbreeding can be very high indeed. In case the common ancestor are inbred, the inbreeding coefficient is calculated as follows F = Ʃ (1/2)n1+n2+1 (1+F ancestor) 4. The phenotypic outcomes of inbreeding have been the focus of several reviews, in both captive and natural popu-lations. Inbreeding was a common practice for elite pure-blood wizarding families wishing to uphold the tradition of marrying only wizards of respected ancestry. Figure 16.

Outbreeding - Download as a PDF or view online for free. This occurs even if mating is random within subpopulations [d]. From this, the allele frequencies can be calculated, and the expectation of () derived : = + (() + + ()) = = = = / = / () = The different F-statistics look at different levels of population structure. . inbreeding: 1 n the act of mating closely related individuals Type of: conjugation , coupling , mating , pairing , sexual union , union the act of pairing a male and female for reproductive purposesIn the same way that inbreeding among human populations can increase the frequency of normally rare genes that cause diseases, the selective breeding that created the hundreds of modern dog breeds. Available evidence suggests that congenital and genetic disorders are responsible for a major proportion of infant mortality, morbidity, and handicap in Arab countries. As a result, any seedstock producer is practicing some inbreeding. In inbreeding. It can be done with or without accounting for breeding values. Inbreeding results in an excess of homozygotes and hence a deficiency of heterozygotes. When this happens, an organism is described as inbred or purebred. The inbreeding load for child survival experienced a pronounced decrease from 3. inbreeding definition: 1. In clinical genetics, a consanguineous marriage is defined as a union between two individuals who are related as second cousins or closer, with the inbreeding coefficient (F) equal or higher than 0. The poor fitness of selfed offspring should counteract any evolution towards selfing, despite its potential to alleviate the negative consequences of pollen limitation. It is generally accepted that the founding population size of Homo sapiens was small, with effective population estimates ranging downward from ≈10,000 to 1,900–2,800 and ≈1,000 to ≈700 (1–4). The Spanish House of Habsburg came to power during the mid-1400s and remained there until the mid-1700s, but during that time, there was quite a bit of inbreeding. Create a new . We don't need to tell you that inbreeding is a bad idea. Three different biological meanings of inbreeding are discussed in this paper: (1) inbreeding as a measure of shared ancestry in the paternal and maternal lineages of an. Introduction. Inbreeding is breeding of two similar parents to produce an offspring with similar traits. Does inbreeding really lead to deformities and diseases? Could inbreeding actually be a good thing? Greg Foot finds out the answers. 50. Inbreeding to remove the “bad genes” increases homozygosity in the population overall, decreasing the diversity in. First cousin to first cousin: 6. In flowering plants, inbreeding may occur either within a single flower, known as autogamy (intrafloral selfing) or between flowers derived from one individual, known as geitonogamy. The Institute of Canine Biology indicates that dog breeds with more than 5% inbreeding are at increased risk for smaller litters and reduced fertility. Outbreeding refers to matings between individuals from different populations, subspecies, or species. (Where, F 1 =first filial. Line-breeding is the tried-and-true method for beginners to create consistent lines of show rabbits, while the risky nature of inbreeding is best left to professionals. This tactic was used many times to develop and improve breed bloodline quality. Genetically similar offsprings are produced. Inbreeding depression has been observed to occur in wild animals with severe consequences [ 2, 3 ]. 1. This form of self-incompatibility has been studied intensively in members of the mustard family ( Brassica ), including turnips, rape, cabbage, broccoli, and cauliflower. If d < 0, inbreeding will increase the mean • For multiple loci, a decrease (inbreeding depression) requires directional dominance---dominance effects d itending to be positive. Inbreeding is a desirable way to strengthen dog. Full sib mating and back crossing of the progeny to the younger of the parents are often practiced. Worldwide, fewer than 9% of people have blue eyes. Historically, western scholars believed that the incest taboo—long proposed as a cultural universal —is vital to understanding the human condition. Inbreeding Outbreeding: Mating of more closely related individuals. Inbreeding avoidance, where animals avoid mating with related individuals, is commonly assumed to be adaptive and a driver of the evolution of mate choice based on genetic (dis)similarity 2,3,4,5. and more rural states. PURPOSE Complimentarity- the phenomenon under which the progeny inherits advantageous traits from the both parents SIRI COW (the pest resistant, highly adapted to the terrain) JERSEY BULL (known for milk production better than Siri and high fat content) JERSEY-SIRI XBRED (milk yield better than Siri, resistance and adaptability better. b) Strain Formation: Developing a small group of animals within a breed and variety with a special character in view. If we liked a trait in a flock, these properties can be maintained by inbreeding. It goes against the biological aim of mating, which is the shuffling of DNA. The coefficient of inbreeding (F) is used to define the probability that two alleles will be identical and derived from the same forebear. brings out hidden genetics. Inbreeding is mating of closely related organisms. Other factors such as outliers and founders will influence the. Inbreeding is a genetic concept that most aquaculturists have heard about, but few understand what it is or know how it can be used or abused. The reasons why inbreeding is bad (disadvantages of inbreeding) are as follow: Adverse effect on the growth rate of animals: When inbreeding is continuously or intensely carried out, the growth rate and mature weight of the offspring (progeny) is negatively affected. The average inbreeding based on genetic analysis across 227 breeds was close to 25%, or the equivalent of sharing the same genetic material with a full sibling. For context, between 25 and 40 percent of people fall in. Inbreeding is defined as mating of two individuals that are closer related than two randomly chosen individuals of the respective population. The degree of genetic relation between two individuals depends on the number and the position of common ancestors in their pedigree and can be measured by calculating the "coefficient of inbreeding" (COI. inbreeding is asymmetrical skull development. 3 and 0. Heterosis comes from cross-breeding while inbreeding occurs in purebreds. Here are five of the worst examples and outcomes of SeaWorld's captive breeding practices: 1. 2. See examples of INBREEDING used in a sentence. Our study provides DNA-based quantification of the prevalence of EI in a European ancestry. The purpose of this clinical report is to review the characteristic head shape changes, as well as secondary craniofacial characteristics, that occur in. It was more commonly done in the past as part of strategic diplomacy for national interest. The objective of this paper is to present to scientific and professional public the most common forms of inbreeding appearing or carried out with different kinds of domestic animals. 5. verb in· breed ˈin-ˈbrēd inbred ˈin-ˈbred ; inbreeding transitive verb : to subject to inbreeding intransitive verb : to engage in inbreeding Examples of inbreed in a Sentence Recent Examples on the Web Imagine a study in which subjects are chronically cold, sleep-deprived, inbred, and held captive in cramped conditions. The Good Side of Inbreeding. Without careful management, selective breeding can reduce species variety and even lead to. It was more commonly done in the past. While some animals have significant levels of genetic variety by nature, others have defences against inbreeding including social behaviour or partner choice. Co, a hub of “expert-created education content,” inbreeding can lead to a host of side effects ranging from smaller adult size and reduced fertility to an increased risk. The scientific definition of inbreeding is below. Animals often don’t have those concepts and it doesn’t. Growth, Development and Reproduction of Organisms - High School. Inbreeding depression. inbreeding and outbreeding. The poor fitness of selfed offspring should counteract any evolution towards selfing, despite its potential to alleviate the negative consequences of pollen limitation. It allows for a faster growth rate. A study of cheetah skulls in museum collections showed that their skulls are relatively asymmetrical. System # 1. Inbreeding is the mating together of closely related dogs, for example mother/son, father/daughter and sibling/sibling matings. Uses of Inbreeding Inbreeding can have benefits to a seed stock producer if the breeder understands how to monitor it and is willing to sacrifice some performance in the process. However, while inbreeding may not be a good idea for humans, for other species, the practice is not nearly as dangerous. They have an inbred love of freedom. Inbreeding happens when individuals who are closely related produce offspring together. It can have harmful effects on the animal’s health, physical appearance, and behavior. . In large natural populations with a high genetic differentiation, crossing between unrelated individuals occurs most frequently. In the broad sense, all members of a breed are related. Over time, natural selection weeds deleterious alleles out of a population — when the dominant deleterious alleles are expressed, they lower the carrier’s fitness, and fewer copies wind up in the next generation. It reduced immune function. e. Pediatric care providers, pediatricians, pediatric subspecialty physicians, and other health care providers should be able to recognize children with abnormal head shapes that occur as a result of both synostotic and deformational processes. Inbreeding (also referred to as “consanguinity”) occurs when mates are related to each other due to incest, assortative mating, small population size, or population sub-structuring. Common alleles become more concentrated — the gene frequency increases in other words — and animals become more and more closely related with each generation. The chapter emphasizes the intimate connection between inbreeding and hierarchical population structure as measured by the F. Match the statements to whether they are an advantage or disadvantage of inbreeding or selfing. Close inbreeding: mating between first order relatives such as full-siblings or parent and offspring, often referred to as incest. This can include mating between siblings, parent-child mating, or even mating between first cousins. Inbreeding is when the animals bred are very close relatives, such as siblings. Inbreeding: Inbreeding refers to the mating of closely related animals of the same breed. Does inbreeding really lead to deformities and diseases? Could inbreeding actually be a good thing? Greg Foot finds out the answers. 1 day ago · The median inbreeding (F_{ROH>5}=0. Tags > Theme > Other Elements > Pregnancy > Impregnation > Inbreeding. Understanding the impact of, and factors influencing, inbreeding in populations of conservation concern has been identified as an important issue for conservation practitioners [23-25]. This is the appropriate approach e. When inbreeding populations occur there are different levels of inbreeding extremes that can arise. For example, there is a famous cat by the name of Fan Tee Cee. Carnal intercourse with sisters by the same mother, with (unmarried) maidens, with females of the lowest castes, with the wives of a friend, or of a son, they declare to be equal to the violation of a Guru's bed. The terminology becomes a bit fuzzy when crossing half-brother, half-sister or cousins, aunts, uncles and. He or she held the titles “Lord of the Two Lands” and “High Priest of Every. It occurs as a result of cross between two closely related parents. Inbreeding thus has serious negative effects on overall animal performance and profitability. This includes sire to daughter, son to dam, and brother to sister. The closer the relationship, the greater the chance of inbreeding. 2. Cloning is the least reliable form of reproduction. But recessive deleterious alleles. Inbreeding has been a common practice in companion animals (and other domesticated species) as it increases the likelihood that animals. Inbreeding promotes the accumulation of good genes while deleting unfavourable ones. Inbreeding is the mating together of closely related dogs, for example mother/son, father/daughter and sibling/sibling matings. Preserving the desired properties. This is a mild form of inbreeding. Birth defects caused by inbreeding were rampant in royal families from Russia to Portugal and even in ancient Egypt, where the practice of sibling marriage was considered godly behavior. As expected, the. In the same study that we have mentioned above, the researchers found out that 227 canine breeds (comprising 49,000+ dogs) have a 25% inbreeding coefficient. Inbreeding is the mating of related. should also be included when determining the “costs” of inbreeding, and a chapter discussing clinical evidence regarding the dysfunctionality of families in which sexual incest has taken place. Harrison et al. Inbreeding is breeding brother to sister. ). It was found that of those 125 people, at least one parent was a first- or second-degree relation of the other (aunts, uncles, etc. Systems of Breeding: The ultimate aim of the breeder […]What indicates inbreeding? The coefficient of inbreeding (F) for a child of a consanguineous marriage is the probability that the child receives two alleles at a given locus that are both from the same ancestor and are, thus, identical by descent (autozygous). Increased inbreeding may affect fitness and decrease the mean performance for economically important traits, such as fertility and. Advantages of Outbreeding: Growth of more desired and a combination of characters. Download KukuFM - code - SUNO50(Coupon valid till 31st May)And as we all know, inbreeding is a very bad idea. There are again two types of inbreeding which are: Inbreeding is the mating of closely related animals to increase homozygosity within a population. Inbreeding is the process of mating individuals that are closely related to each other. Also, Inbreeding may expose harmful genes. The only certain conclusion I can offer is that inbreeding is devastating to a population's color diversity. As of 2003, an average of 45% of married couples were related in the Arab world. Humans 01 January 2018. Bed bugs, small wingless insects that feed solely on blood, are increasingly becoming a problem within residences of all kinds, including homes, apartments, hotels, cruise ships, dormitories and shelters. Most folks would consider these things to be positive, but not all things are good to all flocks or at the very least are not the main priority of the flock owner at the time. Inbreeding affects health. Gai, J. However, it requires that both sentences are fed into the network, which causes a massive computational overhead: Finding the most similar pair in a collection of. Destroying habitats can reduce the size of local populations of many plants and animals. A third line of evidence for inbreeding comes from cheetahs’ high homozygosity. inbreeding will also occur purely because population size is restricted and genetic drift results. Moderate inbreeding: Mating between second order. Inbreeding depression results due to fixation of unfavorable recessive genes in F 2, while in heterosis the unfavorable recessive genes of one line (parent) are covered by favorable dominant genes of other parents. Name the breeding strategy is used to overcome productivity loss asked Jan 29, 2021 in Strategies for Enhancement in Food Production by Nadaa ( 52. Science has shown that the children of an inbred family often have much shorter lifespans and are pl. The researchers found that inbreeding in humans causes physical and mental problems, though the severity of those effects was somewhat limited. 1. Identify a case of corporate fraud by finding a current event or by researching historical cases. 083 between FGRM and FPED. But it has an interesting history. ii) It helps in accumulation of superior genes and elimination of less desirable genes. SeaWorld breeds its orcas way too young. Inbreeding depression per 1 % animals are small in size and others tend to be short and increase of inbreeding was predicted to be up to –30 kg Breeders make less profit, because of the small size or the milk, -1. Some chickens lay smaller eggs or eggs without the outer shell, other chickens can have changed behaviour or are more likely to die from. In some animals productivity is lost due to continuous inbreeding process 1. ) The loss of genetic diversity (i. Recessive traits affect the offspring. Definition. [7] have performed an in-depth investigation into inbreeding depression in an endangered bird, and show that the costs of inbreeding can be very high indeed. a situation in which plants, animals, or people are produced by breeding between closely related plants, animals, or people: the. It sounds like the only. Inbreeding leads to reducing fertility. outcrossing 5. (Comparatively, the child of two first cousins would have an inbreeding coefficient of . Inbreeding and Inbreeding Depression. Although hybrid crop varieties are among the most popular agricultural innovations, the rationale for hybrid crop breeding is sometimes misunderstood. 1 nomic importance does influence the relative emphasis that should be placed on various traits in an inbreeding program. The coefficient of inbreeding is also calculated by counting the number of arrows connecting the individual through one parent back to the common ancestor and back again to his other parent by the following. 7k points) Inbreeding in Gymnosperms. The correlations between FPED and FROH using four classes of ROH lengths ranged from 0. In the same study that we have mentioned above, the researchers found out that 227 canine breeds (comprising 49,000+ dogs) have a 25% inbreeding coefficient. Continued inbreeding results in offspring that are very genetically alike. The incest taboo is one of the oldest and most perplexing mysteries encountered by students of human society. This inbreeding may lower the population’s ability to. 1. Inbreeding is useful in the retention of desirable. (NASA) Adam and Eve might have managed it in the Bible, but scientifically speaking, would two people be enough to repopulate our world from scratch, despite the inevitable health issues associated with inbreeding and a limited gene pool? First of all, let's deal with the obvious problems. Advantages - It increases homozygosity or pure lines.
