::I asked this once on the Rat snake forum ...
::My black rats father is an all white snake, like pure white! I asked if it was a luecisic snake and they said no, just a plain albino. He did have red eyes but man was he white ...

Ryan and Sheila at SCALES in Leader, Sask., have such a snake. His name is "Voodoo" and I've got one of his albino daughters, "Lacey" (also one of his het sons, "Goliath"). As a hatchling, Lacey was pink with peachy-red blotches. Now that she's a year old, her colour is fading, and R&S tell me that eventually she'll be as white as her papa.

:The father of your black rat snake may be both leucistic and albino.

Could be, but not necessarily. Voodoo isn't leucy, I asked R&S about that, and they said that he isn't.

:Black rat snakes have two independent albino genes. AFAIK, the mutants produce very similar appearances. Mutants like these are called mimics. One mutant is called tyrosinase negative albino, and the other is called tyrosinase positive albino.

My 14 E.o.o. babies that hatched on Aug 25 '02, include three albinos. At this point, they look very much like Lacey looked nine months ago when I purchased her. How will I know whether they're T+ or T-, and how do I determine which type Lacey is?

:Tyrosinase negative albino x amelanistic corn produces amelanistic (or albino if you prefer) babies. A couple of years ago a poster here on the kingsnake.com forums had a picture of such a hybrid. Tyrosinase positive albino x amelanistic corn produces normal looking babies.

Would hybridizing one of them to an amel corn be the only way that I could tell for sure, then? Will I also have to breed a hybrid clutch from Lacey to determine which type she is, before deciding whether to mate her to Goliath, or to one of the unrelated babies, to have her produce albino babies?
