This is because it predisposes to homozygosity. Potentially harmful recessive alleles — invisible in the parents — become exposed to the forces of natural selection in the children.

WebApr 9, 2024 · Emily Kantner Apr 9, 2024. Spend much time at deer camp, and you’ll probably hear a hunter blame wonky antlers, piebald coloration, and other genetic abnormalities on inbreeding. But the science says incestuous mating usually isn’t to blame, and inbreeding is a nearly insignificant concern for whitetail hunters. WebInbreeding generally has deleterious effects because it causes more recessive genes or alleles to become homozygous (have two identical alleles because of descent from the same ancestor). Experience shows typical inbred mammals to contain four or more loci homozygous for deleterious alleles.
