Each of your cells contains two copies of 23 chromosomes, one inherited from your father and one from your mother. Theoretically, when you create a gamete — a sperm or an egg —  each copy has a 50-50 shot at being passed on. But the reality isn’t so clearcut.

Congenital heart valve defects appear in 2 percent of all live births, making them the most common type of birth defect.
