WebSep 1, 1999 · Inbreeding depression is the decline in the value of a trait as a direct consequence of inbreeding (Wright, 1977; Shields, 1987). The most common estimates of … WebInbreeding is the mating of individuals related by ancestry. It is measured as the probability that two alleles at a locus are identical by descent (F). Inbreeding increases homozygosity and exposes rare alleles. When parents of an individual share one or more common ancestors (i.e. are related), the individual is inbred.
