I know that Axanthics are simple recessive, that there are different lines of them, and that the different lines are not compatible. So if, for example, you bred together a VPI Axanthic with a Joliff Axanthic, you'd get all visual normals because all of the babies would be het for both lines, but not homozygous for either line and therefore not displaying the Axanthic trait. Is all that correct?

What I'm wondering is if anyone has tried to produce a snake that is homozygous for 2 or more of the different Axanthic lines? This might not be possible, depending on whether the different lines are mutations at the same or different loci (I hope that is the right word).

I was thinking that if such a snake could be produced, it might have less tendency to brown out than a snake that carried only 1 Axanthic line.
