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. WebAnswer: For a given allele, inbreeding increases the proportion of homozygotes in a population. 34) In zoo animals, inbreeding often occurs because of a lack of a sufficient pool of breeding individuals. ...
