WebIn the short run, an increase in inbreeding increases the probability with which offspring get two copies of a recessive deleterious alleles, lowering fitnesses via inbreeding depression. [22] In a species that habitually inbreeds, e.g. through self-fertilization, a proportion of recessive deleterious alleles can be purged.

WebInbreeding is the mating of related individuals, either close or distant.
