This could just as easily apply to Alterna.
First, you didn't answer my question. How many kinked up hatchlings do you see in the wild?
As for the first question, not really, for my part. I'm sure that they naturally disperse to close-by locales, and of course, you'd find fewer there if the phenotype was less fit for the environment, but you'd still find them on the fringe.
"to close-by locales" Correct me if I am wrong, but I think the first one west of Fresno will be about 7 to 10 miles and the next one 12 or so and the next one would be about 17 miles. If they started to drift naturally outside their range, I would think they would turn up closer and more often near that fringe.
i.e. If the mutation is selected against west of their yellow limestone habitat, then that would explain seeing fewer. And, of course, no one was legally hunting TPRSs from 1977 until 1987. That could explain why people weren't seeing them there until 1990 with any regularity.
I saw a heck of a lot more people "not" hunting from 77 to 87 than I see "not" hunting there now. If they crossed the road back then, there would have been a lot more people there to "not" see them.
The remarkable thing is that it appears to be a recessive morph that is selected for and at least as equally fit as normals in that area.
I have collected 2 gravid female blonds, both laid and produced 100% blond babies. As you know, that means they bred to a blond male. The chances of that are astronomical, so is that a sign of natural selective breeding for a particular color morph?
Hey Dusty, as for your Question, email me and I will answer it.
Later
