>re: pyro hypos, didn't jeff breed one x the other and get no hypos? and since each of the hypothetical two types (barczyk, sentz) have bred true as recessives to the best of my knowledge, that hypoB X hypoS pairing producing no hypos wouldn't be possible if there aren't two diff morphs, or alleles, would it?
Getting no hypos from this type of mating would prove that the two mutants are independent and not alleles.
IMHO, the most likely hypothesis for the extremes is the two independent mutants acting in combination. When I was working in a breeding colony of ringneck doves, we had blonds and ivories that were both lighter than the normal doves. Combining blond and ivory produced birds that were lighter in color than either blond or ivory.
I'd really like to see someone take a good look through a microscope at various mutant snakes' skin. The melanin pigment cells in the mutants might have different shapes than the normal melanin pigment cells. And the pigment granules in the cells might have different size, shape, density, or number. Or the melanin pigment cells might simply be less efficient than normal at producing tyrosinase.
Theorizing won't get us anywhere unless somebody tests the ideas. We need data most of all.
