WebAs inbreeding increases, the probability of being homozygous for one (or more) of these lethal alleles also increases, causing fitness to decline. However, as those lethals begin to … WebInbreeding reduces survival and reproduction (i.e. it causes inbreeding depression), and thereby increases extinction risk. Inbreeding depression is due to increased homozygosity for harmful alleles and at loci exhibiting heterozygote advantage.

WebInbreeding is the mating of related individuals, either close or distant. The more inbred a dog is, the higher the chance that the same version of a gene has been inherited from both dam and sire – both for desirable and undesirable traits.
