Please excuse my dust while I revamp this section
There are only two genes in this gene set, B (black) which is dominant and b (chocolate) which is recessive. Colors in the B (black) set include black, blue, tort, sable point, and chinchilla. Colors in the b (chocolate) set include chocolate, lilac and lynx. Because there are two genes in this set, there are three possible gene combinations: BB, Bb and bb. BB & Bb will both show the black. The only way for the chocolate to appear in the bunny is if this gene set is bb. If you are breeding to obtain one of the chocolate colors, it is best to use a chocolate color rabbit. It’s not impossible to get a chocolate from a black rabbit since both parents could carry the chocolate gene, but it’s a whole lot easier when starting with a chocolate.
