WebInbreeding 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 … WebInbreeding is a cumulative phenomenon and in the course of successive generations it increases homozygosity by 50% and reduces heterozygosity by 50% in F1, 25% in F2, 12.5% in F3, and 6.25% in F4. What causes homozygosity? You inherit two alleles for each gene. One comes from your biological mother and one comes from your biological father.
