[QUOTE="alexfarms, post: 648196, member: 8677"] A black hided simm/Angus that appears normal should not carry the diluter gene(which causes rat tails). No normal appearing black animal will carry the diluter gene. No red animal will express rat tail, but they can carry the gene. Rat tail and hypotrichosis are two different abnormalities. The rat tail gene is a dominant gene that can only be expressed if the animal also carries the black gene. The hypotrichosis gene is simple recessive. Animals that are homozygous for the hypotrichosis gene will have short, kinky, thin hair at birth and will usually look better as they age. I only had 1 hypotrichosis animal and it sure didn't perform as well as its contemporaries. The rat tail gene isn't being passed on by normal appearing black cattle, it is being passed on by cattle that are other than black and carry the rat tail gene without expressing it themselves. It became common in the US after the appearance of the continental cattle, so they probably brought it in. [/QUOTE]
