WebConsider two alleles, A, and a with frequencies p,q with inbreeding (IBD) at rate F: Frequency of homozygotes: AA = (1-F)p 2 [outbred] + Fp[inbred] (see figure at right) = p 2 + F(p-p 2) = … WebContrary to common belief, inbreeding does not in itself alter allele frequencies, but rather increases the relative proportion of homozygotes to heterozygotes; however, because the increased proportion of deleterious homozygotes exposes the allele to natural selection, in the long run its frequency decreases more … How bad is inbreeding in dogs?
WebAllele frequency is the proportion of a particular allele in a breeding pool. According to a simple application of Hardy-Weinberg - two alleles, with complete dominance of one over the other - the equation is p^2 + 2pq + q^2, where p is the allelic frequency of the dominant allele, and q that of the recessive allele.
