I get that, and those bulls don't belong on Simmental cows or other cows that might have a spot gene, but on Angus cows which DON'T carry a spot gene (which is recessive), a bull like that would sire black baldies & blazes...NOT spotted calves. It's the same concept as running a Hereford bull on Angus cows or vice versa...nobody would be afraid those calves would look like one parent or the other...we know that mating will produce a black baldy calf with great consistency & predictability. Since we don't know as much about some of the genes that cause spotting or blaze faces, it's more difficult to predict for our commercial customers what will happen, but we know what Angus genetics will dooms far as color patterns, and my theory is that the baldy & blaze genes in Simmental are connected to the spot gene. If that's true, a bull that's homozygous for spotting will pass that gene to every calf, and on cows that DON'T carry a spot gene (which is recessive), we would be able to predict a high percentage of blaze faced calves. What would be more uniform than a whole calf crop of black, blaze faced babies? I admit it will take a progressive commercial guy who understands genetics and is willing to trust in that theory...I just wish I had about 50 Angus cows and a black & white spotted, homozygous black bull with goggle eyes. When I find that bull, I'll feel like it's Christmas morning! Lol
