Final answer:
Temperature sex determination is a process in which the sex of certain reptiles is determined by the temperature at which their eggs are incubated.
Step-by-step explanation:
Temperature sex determination is a process in which the sex of certain reptiles is determined by the temperature at which their eggs are incubated. This phenomenon, known as environmental sex determination or temperature-dependent sex determination, occurs in reptile groups such as alligators, some turtles, and tuataras. For example, in many turtles, cooler temperatures during egg incubation result in the production of males, while warmer temperatures produce females. Similarly, in certain crocodile and turtle species, moderate temperatures produce males, while both warm and cool temperatures result in females.
