: Paul,
: Where is the proof that the T- albino is actually T-? Other than "because everyone says it SHOULD look that way," do you have any data? A harder question would be on the T+.

Bern Bechtel did a paper in the Journal of Heredity sometime in 1985 about black rat snake mutants. He said that there were two independent albino mutants in the BRS, a tyrosinase negative and a tyrosinase positive albino. Bechtel has tested the amelanistic corn snake and determined that it is tyrosinase negative. I don't have the reference handy, but it is in the bibliography at the end of one of the chapters in Bechtels reptile and amphibian variants book.
