Pet Genetics

I have noticed that when messing with the genetics in CAS, I would, occasionally, very rarely get a different color between two pets. For example, I kept randomizing kittens between a bengal cat and a siamese and I got a solid tan kitten. Otherwise, they had bengal coats or siamese coats. I am disappointed that the genetics don't mesh, in dogs, however, the genetics seem to be a bit more active. When doing the same with two different dogs, the puppies coats would all come out different. I goy a brindle pup out of a Saint Bernard and a boxer. The dog, which i added to my family when I made it, looks like a SB, but is brindle and white.
