[QUOTE="randiliana, post: 730738, member: 2308"] Whoops, I think we have a misunderstanding. [b]spotting gene which shows up ONLY when an animal is homo [/b] Means that the spots only show up when an animal is homo for the SPOTTING gene. Not homo for the BLACK gene. A HOMO BLACK animal is homo for the black color. S/He may or may not carry other genes. You can have a homo black animal that is spotted, or that looks like a hereford or that is grey. All the homo black means is that the animal has 2 copies of the Black gene. In your case it sounds like you have a homo black bull that either carries the recessive spotting gene or some other gene that puts white on the belly. He will only pass this gene on 50% of the time because he is hetero for it. But he will ALWAYS pass on the BLACK gene. Since you bred him to some reds, the calves will all be black. Whether they have any white on them will depend on BOTH parents. The sire will have to pass on his recessive gene, and so would the dam(if she actually carries the same gene) for the calves to have white on them. I know that the odd animal in the Gelbveih breed can show up spotted. Neighbour up the road who raises Gelbveih says that there are some spotted animals in the breed. Not common, but they are out there. They have a spotted cow which had a spotted calf a few years ago. [/QUOTE]
