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 WebThe coefficient of inbreeding, F, is the probability that a person with two identical genes …
