I'm not sure I want popular opinion on my side -- I've noticed those with the most opinions often have the fewest facts.

Is that a baby black rat snake?

From the eye and skin, it's got melanin. Too much to be a tyrosinase positive albino, IMHO. But I don't know which mutant it has.

I think it's a beautiful snake.

Hypo might be more appropriate than albino. But I'm not up on useage in Baird's rats.

Regardless of the form,is not a trait that is expressed in "degrees"...In other words,when expressed in their homozygous state,which is the only condition in which they are visible,both tyrosinase negative & positive forms of amelanistics are quite obviously albinistic in appearence.(notable exceptions in boas,for example,often refered to as "paradox" are in fact examples of a defect within a defect,in which the biochemical process that would normally block,or,inhibit certain types of tyrosinase production,are,for reasons not fully understood,"incomplete",ie;"defective".) the animal in your post above,may come from a line that produces albinos,but,I see no evidence from the photo that is expressing any known form of amelanism.(sometimes T positive albinos are at first confused with hypomelanistic expression,(and,vice versa.)however,one quick examination of the eyes usually erases all doubt,T positives have ruby red pupils,sometimes the use of a small flashlight is neccessary to truely see this,with small colubrids.)

hypo and not amel.....as far as definitions go.....

if you want info on her and a whole discussion.....see ratsnakes forum

seems to be more educated guesses and explanations.....

anyway....she is mine and i love her lol

hypo....amel (as she was sold to me) or whatever

she definatly has no black.....as in "black" definition....but also doesnt have an amel eye either.....

beautiful morph anyways

Bechtel's book says both black and brown are products of melanin.
