>>More correctly stated, Normal is dominant to all other known cornsnake genes. (There's some question about whether 'bloodred' aka 'diffuse' can be considered co-dominant to normal, since a partial effect is often observed in animals which are het.)

>>In addition to Normal's dominance, the following atypical gene interactions exist. Motley is dominant to Stripe -- a cornsnake het stripe, het motley will appear to be Motley. (This is different from the partial striping that striped-motleys exhibit.) Also, Ultrahypo is co-dominant with Amel -- a cornsnake het ultra, het amel will appear to be somwhere inbetween hypo and amel, and is known as an 'ultramel'. All other gene interactions beyond these special cases appear to be plain ol' recessives with no odd alleles. So far.
I will not dispute any of that, as she knows FAR more than I.
But genetic terms are used in a terrible manner. Co dom for corns may not be the same as boas. And IS NOT. Hypo is so called Co DOM in boas, although I believe it is dominent to normal. Which means you can have a het for normal, although a customer of mine says technically it is double het! I surrendered a while ago, to try to TOTALLY understand this.
But "co dom" "should" mean both traits show, (famous red and white rose) where as "incomplete dom" (famous pink rose) is one or the other shows.
Confused? it gets worse. Co dom genes can act like incomplete. And genes at adjacent alleles can effect that allele in various manners or degrees.
I only bring this up if you are looking at various species of snakes. Terms are not used universal. And this is the accepted practice, which makes no sense.
Similer idea of the same thing is corns are Amels while boas are albinos.
I hope I got that mess right, and did not confuse the issue more. But, one must be aware that not all herps use the terms the same.
