Everyone knows you got black baldies out of red herf and black angus matings, but why we are not seeing more white faced calves in the matings of black herf and black angus? I have always thought that white face gene is dominant?
Think of a punnett square, W=white face, dominant w=no white face, recessive
Dam(black baldy):> W w
Sire (black angus):v w Ww ww
w Ww ww
The point: There is a 50% chance that your calf will have a dominant gene for a white face, and a 50% chance that there will be no dominant gene for a white face a.k.a. no white face. This assumes that the cow is an F1 from a 100% black sire (anything homozygous black, holstein, angus, simmental, maine, etc.) and a 100% red hereford and that the bull is a 100% black bull (again, anything homozygous black). Just like if you took a black baldy cow and bred her to a red angus bull, technically there is a chance that you could get a calf that looks exactly like a hereford. Could also happen if you bred a black angus bull to a black baldy cow if the bull is a Red carrier and the baldy cow still has her red gene. I have two holstein x hereford black baldy cows that were both bred to the same angus bull, one had a solid black calf (white spot on udder and white switch) and the other had a black baldy.
Hope this helps clear it up.
