Which of the following determines genetic sex (male or female)in mammals?

Question

Quizplus · Accepted Answer

The SRY gene on the Y chromosome is responsible for triggering the development of male characteristics in mammals. This gene is only present on the Y chromosome, so an embryo with two X chromosomes will develop as female. The other options are incorrect - the Y chromosome is typically only contained in sperm, not eggs; temperature has no effect on genetic sex determination; and the genetic makeup of the parents only contributes to the likelihood of inheriting certain genes (such as the Y chromosome). The acrosome of the sperm is involved in fertilization, but not in determining genetic sex.
