    Okay...long story short.

    Females, I believe are X chromosomes, and males are Y chromosomes.

    When conceived, the male's sperm carries X and Y chromosomes to the egg, which are always X chromosomes.

    If a sperm carrying an X chromosome (aka: Xx) to the egg conceives, the baby will be a girl. If a sperm carrying the Y chromosome conceives (Xy), the baby will be a boy.

    Notice the consistency...all EGGS are nipples are a given either just depends upon the X or Y chromosome from the father on whether the hormones know to grow in the future, or stay flat in the future.

    Hope this helps.
