I'd love to find out if my 3 new rat snake hatchlings were definitely produced by parthenogenesis...I'll have to ask around to see if any vets can test their DNA.
And this article does explain why all such offspring may or may not be clones of the mom, so that would account for the differences in my rat snakes too. I'll
also check their genders, but not while they're this young. Thanks for posting this. Nature is amazing!
