Albino, lavender and caramel differences

[paulh]

Actually, the classic Albino is T- (at least that is the assumption, it may not be true but without sequence data we cannot know for sure) and Lav and Caramel are both T+
.

Double emphasize the word "assumption" there. The classic test for albino is the dopa test, and as far as I know, nobody has done that or any other such test on any boa or python. H. B. Bechtel did dopa tests on the corn snake and a few other colubrids. Recently the amelanistic mutant in the corn snake, which Bechtel labelled as T-, has been sequenced. That mutant is actually OCA2 negative rather than T-. See https://www.nature.com/articles/srep17118
