Inbreeding Depression: The reason behind the adoption of such techniques by plants is that due to continued in-breeding, plants can develop a condition called inbreeding depression, leading to … 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. 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.
