Inbreeding coefficient fis
WebThe INBREEDING COEFFICIENT, F,is used to gauge the strength of inbreeding. F= probability that two alleles in an individual areidentical by descent(IBD). Fstands for fixation index, because of the increase in homozygosity, or fixation, that results from inbreeding. Note: two alleles that are identical WebMay 31, 2013 · From erikscraggs gmail.com Thu May 30 18:46:07 2013 From: Erik …

WebJun 21, 2024 · The graphs below show the distribution of inbreeding coefficients (Fis) in Boxers and Irish Wolfhounds. For both breeds, there is "excess homozygosity" - a higher incidence of homozygosity on average than you would expect to see in a randomly breeding population. In both breeds, breeders are preferentially mating dogs that are more related …
