The Hollow is a 1975 documentary about the inbred hillbilly residents of an area of New York State in Saratoga County known informally as “Allentown” for reasons that soon become abundantly clear. It begins with the following text: Early in the 19th Century two families, the Allens and Kathans, settled in the Southern Adirondack Mountains of …1. Introduction. The genetic load of deleterious alleles segregating in a population is a major determinant of fitness variation (), having consequences for genome variation (Charlesworth 1994), population persistence (Saccheri et al. 1998), the evolution of inbreeding avoidance mechanisms (Pusey & Wolf 1996; Tregenza & Wedell 2002), and heterosis-assisted gene flow (Ingvarsson & Whitlock 2000 ...This study found inbreeding depression for many traits, and when inbreeding was 0.125, the predicted lifetime breeding success in females and males was only 18% and 5%, respectively, of that with no inbreeding. These data gave extremely high estimates of 2 B = 27.4 and 47.9, in females and males, respectively.What we can do is compare changes in phenotypic performance under inbreeding ( Table 1) with rates of genetic gain ( Table 2) to assess the current situation, with the caveat that we are comparing phenotypic with genetic values. Table 1 contains estimates of inbreeding depression for 9 traits included in the Lifetime Net Merit selection index ...

These findings arguably provide the strongest evidence to date of an HFC being due to inbreeding depression in a natural population lacking a pedigree. They also suggest that under some circumstances heterozygosity may explain far more variation in fitness than previously envisaged. Keywords: RAD sequencing; genetic variability; heterozygosity ...

General Overviews. Classical population genetics has long concerned itself with the systems of mating and population structures that generate inbreeding and inbreeding depression, the decline in fitness due to inbreeding (see Early-20th-Century History of Inbreeding Research and Textbooks).Population geneticists exploring the forces that generate and maintain genetic variation analyze how the ...Inbreeding depression refers to the reduced performance arising from increased homozygosity, a phenomenon that is the reverse of heterosis and exists …Inbreeding and its consequences, or the avoidance thereof, play an important role in ecological and evolutionary processes. Progeny of related individuals often are at selective disadvantages within populations (Ralls et al. 1988; Crnokrak and Roff 1999; Keller and Waller 2002; but see Ballou 1997), leading to the evolution of strategies to minimize inbreeding in the wild (Pusey and Wolf 1996).The purpose of this study was to determine changes in genetic diversity as a result of the implementation of genomic selection in Angus cattle and quantify potential …Inbreeding, Hybrid Vigor, and Hybrid Corn.

The two different measures of inbreeding estimated, Wrights fixation index (F, in Table 1, Table 2) and F is, approached zero. These results are by no means unprecedented (Procaccini et al., 2007; Ferber et al., 2008 ), but they contradicted the only other genetic information for eelgrass in Long Island ( Campanella et al., 2010a ).

Approximately 70% of inbred families live in desolate areas. 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.Definition of consanguinity. 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 0.0156 (Bittles 2001), where (F) represents a measure of the proportion of loci at which the offspring of a consanguineous union is expected to inherit identical gene ...The average COI for purebred dogs is ~20%. Specific breeds can be higher or lower than this value. For some breeds, the average coefficient of inbreeding can approach or even pass 40%. Because these are average numbers, individual COI can vary. For example, some breeding lines may have more genetic diversity than others.77. 1. Gamete donation, either egg or sperm donation, is a reproductive option in the United States by which same-sex and heterosexual couples as well as singles can become parents. It should be clear the the USA does not count on specific regulations governing sperm and egg donation but it varies from state to state, that is to say, each state ...Inbreeding coefficients and consanguineous mating types are usually inferred from population surveys or pedigree studies. Here, we present a method to estimate them from dense genome-wide single ...

The Whittaker family inbreeding started with twin brothers John and Henry Whittaker in 1887. John married his own first cousin, Ada Riggs. Later, Ada and John had nine children, including Gracie Irene Whittaker, who was born in 1920.

Scientists were quite intrigued as to the cause of the blue skin (cyanosis) in the Fugate family. In the 1960s, a young hematologist named Madison Cawein traveled to the region with the aim to cure the blue people of their skin color. The doctor hiked through the Appalachian hills on a mission to find the famous blue ...Breeding Program Basics. Evaluating colony performance and making informed selections of breeding stocks requires meticulous planning, rigorous record keeping, and regular inspections.

The analysis of genomic data (~400,000 autosomal SNPs) enabled the reliable estimation of inbreeding levels in a sample of 541 individuals sampled from a highly admixed Brazilian population isolate (an African-derived quilombo in the State of São Paulo). To achieve this, different methods were applied to the joint information of two sets of markers (one complete and another excluding loci in ...

Breeding systems serve to promote and preserve desired genetic traits in a breed or species. Over the past centuries, humans have developed several breeding systems (e.g., pure-breeding, inbreeding, crossbreeding). Each breeding system has unique benefits, and the use of different techniques may lead to different outcomes.Introduction. Mating between close relatives, that is inbreeding, is reported in many species to yield deleterious outcomes, such as reduced fertility 1 - 4, stature 2, 4 - 10 and lifespan 2.In humans, consanguineous mating leads to higher childhood mortality 3, 11, 12 and to adverse effects on traits such as lung function 4, 10, 13 and cognitive ability 4, 8, 10, 13.(Comparatively, the child of two first cousins would have an inbreeding coefficient of .0625, and the child of two third cousins, like England's Prince Charles, would have an inbreeding ... The positive correlation between inbreeding coefficients and distance from Africa was eliminated if heterozygosity was controlled, indicating that the increase in inbreeding coefficient is a manifestation of the same reduction of ancestral population size outward from Africa that contributes to decreasing heterozygosity. Introduction. Inbreeding in US dairy cattle has increased steadily over the past several decades. The average inbreeding coefficient of Holsteins rose from 0.4% in 1970 to 5.8% in 2012 (USDA-AIPL, 2012), with the majority of this increase attributed to intense selection pressure on bulls.Here we examine ancestry, population structure, and inbreeding using SNP microarray genotypes in a cohort of 814 wild mice spanning five continents and all major subspecies of Mus, with a focus on ...Inbreeding drives maize centromere evolution Proc Natl Acad Sci U S A. 2016 Feb 23;113(8):E987-96. doi: 10.1073/pnas.1522008113.
