Some people think that the fetus starts out as a girl and then grows into a boy or stays a girl. They're wrong since embryos are genotypically a boy or a girl at the time of conception. The chromosomes they inherit make them either XX(girl) or XY(boy). Because a female is XX, she will always contribute an X chromosome, but because a male has both, X and Y (XY), the male could either contribute an X chromosome or a Y chromosome. Therefore, the males determine the sex of the baby.
