When two closely related organisms mate, their offspring have a higher level of homozygosity: in other words, an increased chance that the offspring will receive identical alleles from their mother and father. In contrast, heterozygosity occurs when the offspring receives different alleles.

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. WebInbreeding exposes harmful recessive genes that are eliminated by selection. It also helps in accumulation of superior genes and elimination of less desirable genes. Outbreeding is mating of unrelated animals. Generally, outbreeding increases vigour and improves quality of the breed. It also increases heterozygosity. WebFeb 26, 2015 · Inbreeding refers to the mating among related individuals and results in an increase in homozygosity. The fitness costs associated with inbreeding are due to recessive deleterious alleles that confer a disadvantage on the individual possessing them. built ls motor
