[QUOTE="Jessica06, post: 1380533, member: 5612"] Yes, you can get a homozygous black Black Hereford. The red gene is recessive to Black. It's impossible to tell if they aren't DNA tested, since the black hides the red. If you took two animals that were black, but carried red, and bred them together, theoretically you would have a 25% chance of having a homozygous black, 50% chance of getting a heterozygous black (black but hiding a red), and a 25% chance of getting a homozygous red. Black - A Red - a Homo. black - AA Hetero. black - Aa Homo. red - aa Aa x Aa = 25% AA, 50% Aa, 25% aa If you want to make sure you are getting a homozygous black, just make sure he's been coat color tested, or see if he's out of tested homozygous black parents.
