[QUOTE="LauraleesFarm, post: 1074945, member: 14261"] Ryno- IF the cows are registered brangus then they are SUPPOSED to be homozygous for polled. If the animal is actually homozygous for polled, then its offspring will all be polled. BUT its grandchildren (grandcalves?) could crop back up with horns, depending on what the bull was that bred the original homozygous polled cow. Because the added horned gene from the other parent will cause the offspring to silently carry a horned gene. There is plenty written on the subject if you do a google search. You can DNA test for polled/horned genetics as well. That is really the only true way to know for sure. So many in the breed registries could be, shall we say, "tainted" ? Not all breeders are honest. All that being said I am told that some breeds like Longhorn and Watusi will make a LIAR out of a homozygous polled mate. Apparently there are other genetics at play in some of the breeds with outrageous horns. Scurs are an entirely different gene that has nothing much to do with the polled gene or the horned. Even with a homozygous polled parent, scurs can be present in the offspring. [/QUOTE]
