States with the most inbreeding. Things To Know About States with the most inbreeding.

Introduction. 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.
