I'm confused I thought the answer was it is a naturally occuring mutated (or naturally mutating) gene....it just happens that way.
Lady Jane had it right, and Pinehaven did too; such things can be very manipulated with an understanding of genetic.
I used to know a Russian Dwarf hamper breeder she got really into color mutations based off natural mutations of the albino gene any-who she made purple hamsters one time... |
