When undesirable recessive genes appear in the homozygous state (bb), the condition is often fatal. The fatality may occur very early in embryonic development and look like a failed conception to a dairy producer.

Consider 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) = p 2 + Fp(1-p) = p 2 + Fpq Similarly the frequency of the other homozygotes, aa= q 2 + Fpq All genotype frequencies must add to …
