Why Should Breeders Consider Genetic COI in Breeding Decisions?

WebInbreeding increases homozygosity and helps in developing pure lines. But continued inbreeding results in reduced fertility and productivity in animals. This is called inbreeding depression. This can be overcome by crossing these animals with unrelated superior animals of the same breed having no common ancestors. This is called out-crossing. WebInbreeding reduces survival and reproduction (i.e. it causes inbreeding depression), and thereby increases extinction risk. Inbreeding depression is due to increased homozygosity for harmful alleles and at loci exhibiting heterozygote advantage. imsm applicationWebif you are asking whether inbreeding increases homozygosity, the answer is yes because that is how we breed domestic animals to have the genetic characteristics we want. The problem is that inbreeding also increase the likelihood that there is homozygosity of deleterious alleles; those that cause disease or may result in death. ims manutention
