• Sexual characteristics
In mankind, the sex of an individual is generally determined at the time of fertilization by the genetic material carried in the sperm cell. If a sperm cell carrying an X chromosome fertilizes the egg, the offspring will typically be female (XX); if a sperm cell carrying a Y chromosome fertilizes the egg, the offspring will typically be male (XY). Persons whose anatomy or chromosomal makeup differ from this pattern are referred to as intersex.
