      • Male: characterized by the presence of testes, a penis, and XY chromosomes.
      • Female: characterized by the presence of ovaries, a vagina, and XX chromosomes.

    Sex Determination

    • Sex is determined by the presence of sex chromosomes (X and Y).
    • In humans, sex is determined by the following:
