How is gender inheritance?
Gender is inherited from your parent's 23rd chromosome. The (XX) chromosome pair is for a female and the (XY) chromosome pair is for a male.

If you get an (X) from him, you become a girl. If you get a (Y) chromosome from him, you become a boy. This all happens when your mother's egg is fertilized.
