Abyssinian - Salt and Pepper is dominant to Ocicat - Chocolate
Zucchini hides Abyssinian - Salt & Pepper
she bred with Snickers an Ocicat - Chocolate and they had Rasin, an Abyssinian - Salt & Pepper
Rasin bred with Baylie a Tonkinese - Blue Mink, a fur known to be recessive to the other 2, they had an Ocicat - Chocolate.
Since Ocicat - Chocolate is known to be dominant to Tonkinese - Blue Mink it must therefore be Rasins hid and recessive to Abyssinian - Salt & pepper.
