Thanks your message helps a lot... in other words if I make it all up, I won't discover that I've scrunched someone else's toes. Great.... so if I promise to leave all the fancy schmancy letter systems out of it and just tell you the words for it, will you mind giving me a few pointers, for instance if I asked... What would happen if you had a snake that homozygous for amelanism and anerythristic, you could tell me it's a blizzard (or snow, or or or...?) hehe. Anyway, thanks for your informative post, it will help me in getting these guys figured out, at least to a certain degree. It's like a logic puzzle, and I can't stand not figuring those things out, so I'm going to have to get a handle on these corn snake morphs and the genetics behind them, just so I know what the heck everyone is talking about. :)

Thanks again.

:It probably helps that rats and mice had their genomes mapped so thoroughly.

:There are no set standard names or symbols for any cornsnake loci or genes or alleles yet, use what you like.

:If what you really need is symbols, just use "Am, am" for the amel locus and "An, an" for the Anery locus etc.

:To be honest, I absolutely can't stand any of the notation systems used for describing loci or genotypes (the above "paragraph" even gives me to creepy-crawlies) so I don't even care what anyone else uses. I don't want to know about it, or hear about it, or be within 10 light years of it. hehe

:The only traits which have been shown to act as alleles are motley and striped, which are recessive to wild type and codominant to each other.

:The recessives are:
:Amelanistic
:Anerythrystic A
:Charcoal (Anery B)
:Lavender
:Sunkissed (Hypo B)
:Motley/Stripe

:There are some that for the most part act like recessives, but at least in certain bloodlines, it looks like it is possible to make visual distinctions between the het and non-het offspring... IOW, the wild type isn't always completely dominant:
:Hypomelanism
:Caramel
:"Bloodred" (Which is the name applied to both a trait and a selectively-bred morph, joy of joy)
:ZigZag/Aztec

:There aren't any dominant mutants discovered yet.

:There's also no Hypermelanism, hypoerythrism, etc found yet.

:Does that help? ;) (I'm NOT going to make up notation, hehe.)
