TY for your response 2gofrwrd.
I am aware that the Leucistic gene and Patternless gene are different. What I wasn't aware of is that the Leucistic Florida Pine is not a true Leucistic. It makes sense then, the genetic combination of Patternless, Hypo and Axanthic in creating a Leucistic appearing snake. THAT, then would make the Leucistic Florida Pine Triple-Homozygous.

So, 2gofrwrd, it looks as if the Axanthic and Hypo gene do exist in Pines...the Florida Pine at least.
