 Inbreeding can result in inbreeding depression, which is the reduction of fitness of a given population due to inbreeding.Inbreeding depression occurs via appearance of disadvantageous traits due the pairing of deleterious recessive alleles in a mating pair’s progeny.When two related individuals mate, the probability of deleterious recessive alleles pairing in the resulting offspring is higher as compared to when non-related individuals mate because of increased homozygosity.
