How does the temperature of an egg affect its gender?

Here's why:

* Genetics determine gender: In most species, including birds (like chickens, which lay eggs), gender is determined by chromosomes inherited from the parents.

* Males have XY chromosomes, females have XX chromosomes: The father contributes either an X or a Y chromosome, while the mother always contributes an X chromosome.

* Temperature affects development: In some reptiles, temperature can influence the sex of offspring. This is called temperature-dependent sex determination (TSD). However, birds do not have TSD.

In summary: While the temperature of an egg can affect the development of a chick, it has no influence on its gender.
