Abstract

Little is known about reptilian embryonic and sexual development. While lizards display characteristics quite different from other classes of vertebrates, scientists often ascribe mammalian processes to reptiles. The purpose of this study is to examine genital development in a parthenogenetic, all-female lizard species, Lepidodactylus lugubris. Although this species is fully female as an adult, all embryos examined possess well-developed male genitalia. We characterize the extent of cell proliferation in the genitalia at different points in development. This data will be the first step towards telling us whether mammalian processes of differentiation hold significance across biological classes.
