there is some correlation to what Ian is saying, in regards to erythristic animals. In both high red easterns and plains, just about every one ever found was female. In fact Scott sent me one that was supposed to be a male and even that guy turns out to be a female! So now, We do see them born captively (male ery's), but the erythrism seems to favor the females, by a lot. Kind of like how the silver eastern gene heavily favors males. As far as normal wild types of garters.... males and females are pretty equal.
