Isn't the Urban Python the only one with a homozygous toffee ball, or does VPI have one too? I guess you are right about amelanism and axanthism stripping red to a degree. I hadn't thought about that. There are obviously ball pythons that appear to have red. Is it, or is it not known if this is from erythriphore? If it's a fact that it is there, no matter how small the quantity, we should be able to selectively breed for it, even without the jump start of using a recessive, red increasing morph.
