apparently there are 6 species of lizard in that genus that are entirely female.

 

oh and i made a mistake earlier i didn't mean nearly ALL animals, i meant nearly all mammalian animals. so far homosexuality has been observed less frequently in fish, and lizards, though they still occur. aquatic mammals too have also been observed to have some who are born homosexual.

virtually all female, possible.  Having a species that is completely female, however, is impossible.  Animals cannot breed outside their species and produce fertile offspring, so they would need some males inside the species in order to exist

can and does happen (none / 0)
New Mexico Whiptail, as well as several other all-female species of whiptail lizard, does reproduce, and all of its offspring are female. Moreover, it reproduces by parthenogenesis -- its eggs require no fertilization, and its offspring are exact and complete genetic duplicates of the mother.

I claim no special knowledge on gender variation of species...I think there is a big difference talking about mammals vs. reptiles tho.

the way the lizards reproduce causes mutation via genetic drift. so they dont require 2 sexes to mix chromosomes which generate more mutations.
