Inbreeding causes a loss of heterozygosity with no expected change in allele frequencies. Whenever deleterious alleles are at least partially recessive, inbreeding exposes these alleles in homozygotes and causes a decrease in the mean fitness of individuals within the population (Falconer, 1989).

Web1.1.2 Inbreeding. Inbreeding is defined as the probability of two alleles in an individual being identical by descent, and is normally the result of mating related individuals.
