Are you sure? What if I breed a VPI Axanthic to a Snakekeeper Axanthic? Joliff? Nerd? Other new line?
I think I understand what you're trying to say... that a HOMOZYGOUS Axanthic bred to a HOMOZYGOUS Axanthic will yield all Axanthics. That is true as long as the snakes are from compatible lines.
Recessive X Recessive does not necessarily = Recessive.
If I breed a homozygous Axanthic to a homozygous Albino (both recessive), I'm not getting snows or albinos or axanthics. I will get double hets, though.
Axanthic X Axanthic does not necessarily = Axanthic.
If I breed a VPI Axanthic to a Snakekeeper Axanthic, I'm not getting Axanthics. double hets, yes... Axanthics, no.
