(KRO-mo-soam)

A chain of genes. You have 46 chromosomes in each cell in your body, except your reproductive cells (eggs or sperm). The reproductive cells have only 23 chromosomes. When the egg and sperm combine, they produce a cell that has a full set of 46 chromosomes. This is how you pass genes on to your children.
