this could never work because if you mixed any of the white snake genes you wouldnt know what you had unless your bred it. since it would wipe out the pattern and color.

plus it would take longer to breed them than the life cycles of the animals. and the changes would be so low that some ppl have taken more than 7 years to get a double recessive so tripple or quad recessive could take more than 20 years itself. not to mention that it would take more than 1 or 2 animals per morph.
