Role of temperature in sex determination in reptiles to go in Cessnock
When Bull and Eric Charnov, at the University of Utah, in Salt Lake City, Utah, proposed a model for the evolution of environmental sex determination inthey only suggested applying the model to plants and invertebrates, and not to vertebrates. This knowledge may have important consequences in environmental conservation efforts to protect endangered turtle species.

Males, on the other hand, are "heterogametic," with one X chromosome and one Y chromosome. They conjectured that disruptive selection produced by variation in the environment could result in an evolutionary transition from ESD to GSD Bull, Vogt, and Bulmer, Bull, J. Ruggeri, T. Temperature-dependent sex determination in three reptile species: the American alligator Alligator mississippiensisthe red-eared slider turtle Trachemys scripta elegansand the alligator snapping turtle Macroclemys temminckii.
A study found that hot temperatures altered the expression of the sex chromosomes in Australia's bearded dragon lizards.
