Posting this here to avoid hijacking the "cow bred by two bulls" thread.
In reference to Black and Good's hereford bull that throws solids. This suggests heterozygosity for the hereford marking gene (ShS+) instead of ShSh like you would expect. Which may explain how the feathernecks have been bred out more and more in the breed, as Sh is incompletely dominant over solid, so you get the restricted color pattern but a white face.
So, if this is true, there should be solid animals showing up in the hereford breed, as there should be some ShS+ x ShS+ mating occurring.
Are these animals being swept under the rug since they don't meet breed standard, or is the heterozygosity not really occurring in the breed and there is a more nefarious reason for his bulls heterozygous status, or am I missing something in my color breeding knowledge? I am not bashing herefords here, just looking for clarity.
