Well, it could be figured out, but it would take a while to do. If you test breed them with snakes with a known recessive hypo gene, produce the alleged double hets, and later bred those together and produce any "ghost" type animals, then it would prove the snakes in question to be axanthic. Or if you bred them to another totally normal line that is normally ALWAYS yellow and black/brown(never white and black/brown)such as certain yellow coastals and these were also known to NOT be het carriers for any of these traits to give false outcomes, produced hets, then bred them back to each other and produced pure white(possibly bluish hued) hatchlings, it would be pretty obvious that they were indeed axanthic.
But just by looking at some it wouldn't "prove" beyond a doubt that they were truly axanthic unless it was proven first that it was truly a recessively inherited trait.
Now I don't have any idea what the origin of these are, I am ONLY saying that they would have to be proven before you really knew they were truly axanthic, and not merely going by their white bands is all I am saying. The guy could have done this already for all I know, My only point here is that you really can't say they are axanthic by the photo alone without knowing what types of lineage originated them.
Additionally, I saw the same ad Jimmy was talking about and the animals were "said" to be axanthic Cal. kings but looked like crosses with the known axanthic splendidas in the hobby. I don't see the same look in that photo Rainer posted, I am just saying that I didn't believe the ad Jimmy and I saw a good while back as to them NOT having the axanthic gene from splendida. Those looked like DEFINITE crosses to me. I think THAT particular line was indeed a californiae x axanthic splendida cross that Jimmy and I looked at. Not saying this one is or isn't, just that it would have to be proved-out.
