I just read that page, interesting stuff. Do Ball Pythons follow XY or ZW sex determination? I'm not sure. But it still seems to me like they might be male. It would make sense for them to be male, as this kind of thing, adaptively speaking, happens as a result of a female not being in the presence of a male. Because no males are around for sexual reproduction, parthenogenesis becomes a necessity if reproduction is to happen at all. BUT, the logical result of creating offspring would be to create male offspring to compensate for the lack of available males, thus making sexual reproduction a viable option again. That's just my 2 cents, and I'm by no means 100% confident in my hypothesis, but I am reasonably confident, haha. Either way though, it really is amazing.
