I don't know what you've been smoking, but it must be powerful stuff. IMHO, snake genetics is child's play compared to mouse genetics. Show me a snake species with 100 known mutant loci, many loci with multiple alleles with complex dominance relations, and many mimic mutants, not to mention linkage and sexlinkage. At one time I could name nearly a dozen independant mutants that make a mouse spin around in circles. Now all I can remember are waltzer, twirler, shaker, and spinner. And people complain about three independent mutants that reduce the amount of melanin in corn snakes.

As albino in the Cal king is analogous to amelanistic in corns, if it proves out to be sexlinked, then amelanistic in the corn should also be tested. But translocations can move genetic material from one chromosome to another, so it isn't positive proof.

I hadn't remembered just how large the W chromosome is in many snakes. If the Z and W chromosome share a locus, a mutant would be called partially sexlinked. That is harder to test for than a completely sexlinked mutant.

Keep us posted on your king genetics experiment. One generation is probably not enough to identify the mutants involved, though.
