WebInbreeding depression is a reduced biological fitness of the population due to inbreeding. It occurs as a result of crossing related species. The process tends to make the species lose genetic variety. The offspring find it difficult to adapt to changes in the environment. WebInbreeding depression, evidenced by lowered survival rates in offspring of inbred matings, occurs across a wide range of taxa. Inbreeding exposes deleterious recessive genes by increasing the likelihood that both of an animal’s copies of an allele will be the same.
