Step 1 : Introduction to the question "What determines the sex of newborn alligators?"
...Temperature is the deciding factor in an alligator`s gender, according to Dr. Paul Cardeilhac, a professor of veterinary medicine at the University of Florida. Alligators and some turtles are known to display temperature-dependent sex determination (TSD), where the temperature of the environment in which the eggs are raised in determines the sex of the individual. For example in the alligator's eggs, incubation at 34ºC and above produces mostly males, while incubation at 30ºC and below produces mostly females.
