Since this is so rare, would you consider contacting research groups in your area? You'd probably have little difficulty finding a geneticist or herptologist interested in doing the genetic testing to confirm if it is a true case or not (They just see if all offspring are the same sex, and genetically identical) because it's something so rare.

I have some contacts with the University of Tennessee and When they are looking healthy I will probably do that, and then maybe write a paper, though I'm not much on writing.
