[QUOTE="TJSideBiz, post: 1567020, member: 38178"] This is a good basic explanation. Here's another one posted by Rydero on March 13- "Been a few questions about what color calves come out of different combinations how often. I'll explain it how I understand it. If anyone knows something I don't about different combos or breeds or thinks of something I don't please chime in. Each cow or bull has 2 genes for basic color. Black is dominant over red. So for basic red and black cattle you can have - a red animal with 2 red genes, a black animal with one red and one black or a black with 2 black genes. Breed a red to a double black offspring will be black every time. Breed a red to a black carrying a red recessive gene and you'll get half black half red. Breed 2 blacks both with a recessive red gene and you'll get a red a quarter of the time." I'll add this since I don't know how much you may know about genetics-The two color genes they refer to are black and red. The term "dominant" means that it will cover up the other gene (the recessive one) so that you see the dominant one. Offspring inherit one color gene from each parent.
