:can someone direct me to a good site explaining the exact genetics of the different garter morphs?
I'd like to find such a site, too. A it is, I've got more questions than answers. But some of what you want can be dug out of exiting web sites. For example, Scott Felzer's web site has a list of Plains garters. I figure that he has the following mutants:
1) Iowa albino - recessive
2) Nebraska albino - recessive. (Same as John Eddington's easter orange albino???)
3) anerythristic - recessive
The snake(s) in Scott's Iowa albino pictures do not have an obvious yellow dorsal stripe. Is this an artifact or true color? If true, there is another albino that has the orange stripe but is much lighter than the Nebraska garter.
There is a red phase of the plains garter, inheritance unknown to me. Scott's red and christmas albinos. A combination of red and albino??? If so, then red is likely to be recessive to normal.
Melanistic in the eastern garter is a recessive. AFAIK, albino in the checkered garter is also a recessive.
Plenty of mutants still to figure out.
