The sex of a developing sea turtle embryo is determined by 3) the temperature of its nest. This phenomenon is known as temperature-dependent sex determination (TSD), where warmer temperatures tend to produce female turtles and cooler temperatures generally result in male turtles. Genetics also play a role in the overall development and characteristics of the turtles, but the primary factor for sex determination in sea turtles is the temperature during the critical incubation period.
