Sex Determination in Reptiles. Summary of Effects of Constant Temperatures of Incubation on Sex Ratios of Offspring

The phenomenon of environmental sex determination (ESD) in reptiles has been highly publicized in recent years. However, the underlying mechanism(s) that control this process are still poorly known. Additionally, the distribution of ESD within the Reptilia is poorly known, with only 93 of the approximately 6500 species of extant reptiles having been examined for the presence of ESD (Janzen and Paukstis, Quart. Rev. Biol.).
