Inbreeding and Inbreeding Depression - Evolutionary Biology

WebIntroduction. T wo phenomena of increasing importance in zebrafish husbandry are inbreeding depression and its antithesis, outbreeding enhancement or hybrid vigor. Inbreeding depression is observed in many species as the loss of fitness in a population from increasing homozygosity. 1 It can be caused by a general loss of heterozygosity in a … WebUnfavourable genes segregate on inbreeding, and, upon fixation brought by homozygosity, produce lines that possess different gene complexes. Some lines receive more favourable genes than others, accounting for differences observed in the degree of inbreeding depression in different lines. fish tank eclipse
