>What is an amelanistique ? Wich melanine are we talking about ?
An amelanistic corn snake has the red (pyridine based, I think) pigment but lacks the black pigment (eumelanin).
>What kind of tests have been done ? Tyrosine ?.. Dopa ?.. dopaquinone ?.. DHICA oxydase ?.. dopachrome tautomerase ?..
Dopa, I believe. Bechtel had a paper in one of the 1985 issues of the Journal of Heredity about rat snake (Elaphe obsoleta) mutants. That would have details of the test he used, because as far as I know, he used the same test for the corn, too. I'd give the corn snake paper reference, but I can point you to the rat snake reference quicker. I'd have to look up the corn snake reference.
>Are the sharp T positive or T negative ? Any tests done ?
Unknown because no tests have been done, as far as I know.
