That's what I meant. While the female raptors became male and mated in order to reproduce (which actually happens in some animals), Zilla went from male to both male and female at the same time, and reproduced by itself

It would have made more sense for Zilla to be a female and fertilize its own eggs through parthenogenesis, which is actually a real thing, although it occurs in komodo dragons and not marine iguanas. But instead, Devlin and Emmerich decided to make the movie even more scientifically implausible and unrealistic, because they knew stupid people would still say it's better because it's "more realistic," simply because the monster was weaker.
