I am trying to breed for dumbo, as my first venture into rat genetics. I was wondering if dumbo was simple recessive. I have two dumbo males that are in with females right now. Monk, my black hooded dumbo male, is in with an albino female. I do not know her genetic background. Roo, my berkshire dumbo male is in with two hooded females. I do not know their genetic background. I am already aware that the chances of me getting dumbos from any of the females is pretty slim. But if I breed the offspring of Monk to the offspring of Roo, will I possibly get some dumbos?
