WebFeb 26, 2024 · Inbreeding (also referred to as “consanguinity”) occurs when mates are related to each other due to incest, assortative mating, small population size, or population sub-structuring. Inbreeding results in an excess of homozygotes and hence a deficiency of heterozygotes. This, in turn, exposes recessive genetic variation otherwise hidden by ...
