[QUOTE="Travlr, post: 1819518, member: 42463"] It's a little more complicated than that. All calves have a chance of getting any gene from the bull that he carries and will be getting a mix of chromosomes from both breeds, with the sex determinant genes of the bull's offspring from the Y chromosome guaranteed to be from the breed that fathered the bull and the X from the breed that mothered the bull. So a bull fathered by Sim and out of Angus will have the Y chromosome passed down to the calves and the X from the Angus will go to heifers, meaning bull calves will be Sim influenced to the extent the Y is dominant and Heifers will be Angus influenced to the extent the X is dominant. And there are other factors too. But that doesn't mean you won't get relatively consistent calves. If the parents are well matched by type the bull can throw consistent calves. That's one of the problems with Beefmaster. They never established a consistent type. [/QUOTE]
