het snow?

[Carlene16]

Okay, not quite sure I understand this one.

So to be het snow, a ball python has to be het albino AND het axanthic?
Or albino het axanthic, or axanthic het albino?

And it's the same with red tail boas? A boa has to be het albino and het anery, etc?

Not sure if I got that right, just looking for someone to clear that up for me

Thanks!

A "het snow" would be a normal looking animal that is both het albino AND het axanthic...as you guessed.

An albino het axanthic would be called an "albino het snow"...at least, that's how I would refer to it. And Axanthic het snow for the other way around.

Not quite as confident on the boa genetics, but I assume it's similar.

Yup, though I think it's usually written "double het snow" to remind people that there are indeed two genes that the animal is heterozygous for (albino and axanthic).

And the albino het axanthics and axanthic het albinos are often called albino het snows or axanthic het snows, respectively. (Though, of course, if bred together, such a pair could produce all four phenotypes: normals double het snow, albinos het snow, axanthics het snow, and snows.)

Same for boas (only as you say, they are anery and not axanthic). AFAIK the genes for albinism, anerythrism and axanthism are always recessive in all species, though someone please correct me if I'm wrong as I very well could be. (I've never heard of a dominant albinism, that's for sure ...)

Yeah...forgot the "double" part!
