      Nice question. We are all made from a single cell originally, and that cell is usually made by mashing together one cell from out father and one from our mother. Each of these special cells (called gametes) has one half of the genes needed for a new person, so we get a full set. The single cell then divides over and over again until the baby is big enough to be born
