WebRandom genetic driftoccurs in finite populations, even with completely random mating, and leads to changes in both genotype and allele frequencies. Both processes cause a decline in heterozygosity. Smith et al. Why does inbreeding cause a decrease in fitness? What genetic mechanisms, or type of gene action are responsible? WebInbreeding is defined as matings between individuals in a population that are more closely related than expected by chance. The inbreeding coefficient, f, describes the probability that two alleles at a locus are identical by descent.
