Sex Determination in Humans
Explore how biological sex is determined in humans by learning about the role of the X and Y sex chromosomes as well as that of the sex-determining region Y (SRY) gene. You’ll also examine the sexual phenotypes of an individual with an abnormal number of sex chromosomes.
