 Females that are pair bonded to a male of poor genetic quality, as can be the case in inbreeding, are more likely to engage in extra-pair copulations in order to improve their reproductive success and the survivability of their offspring.This improved quality in offspring is generated from either the intrinsic effects of good genes, or from interactions between compatible genes from the parents.In inbreeding, loss of heterozygosity contributes to the overall decreased reproductive success, but when individuals engage in extra-pair copulations, mating between genetically dissimilar individuals leads to increased heterozygosity.
