>So, what leads you to believe this is a dominant trait?
For what it's worth, my definition of a codominant is as follows: An untrained person can spend five minutes looking at normals, heterozygotes and mutant homozygotes. After that, he can sort a mixture of 100 snakes into the three genotype categories with at least 95% accuracy.
From the posts on these forums, the breeders can't do anywhere near that well even after a lot of experience.
Salmon isn't a recessive mutant gene because the heterozygotes do not look normal. And it doesn't fit the codominant definition above. By elimination, it's a dominant mutant gene. It doesn't fit the definition of a dominant mutant gene very well; it's in the gray area between "dominant" and "codominant". "Dominant" is simply the best fit, not a perfect fit.
I've been told that Rich Ihle will have an article in Reptiles magazine in a few months. Maybe we'll get better information then.
