WebInbreeding does not change the allele frequency within a population, but it does increase the proportion of homozygous individuals to heterozygotes. - Because closely related individuals are more likely to share the same alleles, the chance of two recessive alleles coming together during a mating is high. WebInbreeding causes an increase in the probability that individuals carry alleles that are identical by descent. ... migration can rapidly change gene frequencies and increase variation. However, if gene frequencies are changed so that the population is moved farther from equal frequencies of alleles (p=0.5, q=0.5) migration will tend to ...
