WebInbreeding depression also occurs in wild species in natural habitats, and its impacts are typically more severe than in captivity. For example, inbreeding depression was detected … Inbreeding depression is the reduced biological fitness which has the potential to result from inbreeding (the breeding of related individuals). Biological fitness refers to an organism's ability to survive and perpetuate its genetic material. Inbreeding depression is often the result of a population bottleneck. In general, the higher the genetic variation or gene pool within a breeding population, the les…
