Human cells normally contain two sex chromosomes. Females have two X chromosomes, and males have an X and a Y chromosome.<ref>[http://www.dummies.com/WileyCDA/DummiesArticle/id-4097,subcat-MATH.html Genetics: Examining the Basics of Chromosomes]</ref>

After chromosomes are determined, they further influence sex by affecting which [[gonad]]s the [[zygote]] will develop through the Y chromosome. The Y chromosome contains a gene called ''SRY'', which stands for "sex determining region on the Y chromosome." Of course, the SRY gene is absent on the X chromosome.<ref name="psychology in your life"></ref>
