[QUOTE="Cattle Rack Rancher, post: 25140, member: 245"] My mistake F2's would mean you were using a red baldy bull. Let me see. If we call the the white face WH and the none white face wh. First cross WHWH (hereford)x whwh (red angus)=100% WHwh or one WH gene and one wh gene. second cross WHwh (F1) x whwh (red angus) = 50%WHwh + 50% whwh That was easy. If you were using a red baldy bull second cross WHwh (F1) x WHwh (F1)= 25% WHWH + 50% WHwh +25% whwh Looks to me like either cow could be a crapshoot as to whether they are white or red faced next time round Yea, I already know I'm a geek!
