How many traits can a snake carry?

I tend to differentiate between "trait" and "gene" also. Amel and stripe are individual genotypes or mutations, while the thick banding of an extreme okeetee is a trait; it's polygenic. Any phenotype that cannot be outcrossed and recovered through simple Mendelian inheritance I consider a trait.

Ultramel and hypoberry appear to be incomplete dominant in that they both have some amount of visual expression so that their phenotypes are somewhere in between the two, similar to how red and yellow pigments together look orange. This is less obvious in hypoberry until you look at it under a microscope.

That's actually a much easier way to look at it, because it does get confusing. Thanks for the info, I'm gonna keep studying. Lots to learn
