The father's sperm determines the baby's gender. Sperm cells carry either an X chromosome or a Y chromosome, while the mother's eggs carry only X chromosomes. If a sperm carrying an X chromosome fertilizes the egg, the baby will be a girl (XX). If a sperm carrying a Y chromosome fertilizes the egg, the baby will be a boy (XY).

- What chromosome combination results in a boy? A boy is formed when a sperm carrying a Y chromosome fertilizes the mother's egg, resulting in an XY combination.
