I think that the axanthic and anerythristic genes mostly remove pigments rather than adding melanin and the evidence of that is that albinos have yellows and orange colors, but when in combination with the anerythrist or axanthic genes those colors are removed resulting in the snow. This isn't exactly a new concept in snake morphs. We have had this discussion no less than a dozen times and it makes more sense for me to go spend my time discussing global warming with a republican.
