An Example of a Mechanism in Which Sex is Determined

Question

An example of a mechanism in which sex is determined by environmental factors is
A) females are produced from fertilized eggs, whereas males are produced from unfertilized eggs.
B) when the male cares for the eggs, all of the offspring will be male, whereas if the female cares for the eggs, all of the offspring will be female.
C) fertilized eggs incubated at one temperature produce males, whereas eggs incubated at a different temperature produce females. 
D) males will have a Y chromosome, whereas females will not have a Y chromosome.

Accepted Answer

In some reptile species, the sex of the offspring is determined by the temperature at which the eggs are incubated. This is known as temperature-dependent sex determination (TSD). Eggs incubated at a lower temperature produce females, while those incubated at a higher temperature produce males.
