Heterosis, also known as hybrid vigor, is the enhancement of characteristics in the offspring. Inbreeding depression is a reduction in fitness in the offspring as a result of inbreeding. Parents. It occurs as a result of cross between two genetically different parents. It occurs as a result of cross between two closely related parents. 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 feeding frenzy
