There is no reason why you shouldn't breed different species of animal, if you do, the results will very, you won't get a new species, simply a mutation or deformity of a limb or facial feature. if an embreo IS created, it will have the genes of the parent with the dominent allele (UH-LEE-EL) with that trait will be a feature of the offspring. the offspring of the two parents will mostlikely not survive in the womb, so it will not be born.
