From the fact that both animals were pure breds and that ALL the offsprings were black Havana with normal coats we can conclude that black is dominant, we call it B, while white is recessive we call it w, normal coat is dominant we call it N while satin coat is recessive, we call it s. So the 2 originals were BBss & wwNN since they were pure breds. That means that their offsprings can have the following ...
