Eva's Rat Colour Genetics Page - Shaded

Still there are only different color varieties of Siamese and Himalaya in the shaded group. But we are waiting for the Sable Siamese to show up one day on the rat... That will happen when the chinchilla gene of the rat has been found. The shaded varieties are not supposed to be marked. You can breed siamese rats in many different colours, like black siamese, chocolate siamese, mink siamese, english blue siamese, german blue siamese, russian blue siamese and so on. The colour you put on a siamese can not be red/yellow and should be dark.
