I just want to check if I am thinking right here:
I have a girl - black smoke tortoiseshell with white (Norwegian Forest Cat). Her mother is black silver tabby and the father is red with white.
She has one brother who is black and one who is black silver tabby like his mother. BUT she also has a sister who is black silver tabby! As to my knowledge - if you mate a black queen to a red male, all the female kittens must be tortoiseshell to some degree. So I think this black silver tabby girl is really a tortoiseshell genotype, but with so little red that it does not show (fenotype).
Is this correct or have I got my genetics totally wrong here?
