Inbreeding depression biology

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. WebAug 3, 2005 · Inbreeding depression increases under stress in 76% of cases, although this increase is only significant in 48% of the studies considered.

Inbreeding depression - Wikipedia

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… WebInbreeding involves mating of the superior males and superior females of the same breed having no common ancestors. Inbreeding increases homozygosity and helps in developing pure lines. But continued inbreeding results in reduced fertility and productivity in animals.
