Sex determination in humans is primarily influenced by the presence or absence of the Y chromosome. The Y chromosome contains the SRY gene, which triggers the development of male sex characteristics. In the absence of the Y chromosome and SRY gene, the default pathway leads to the development of female sex characteristics. Hormones such as testosterone and estrogen also play a significant role in regulating the development of secondary sex characteristics during puberty.
