Chromosomes Unlike every cell of the male body, which has 46 chromosomes (in 23 pairs), these cells have only 23 (not in pairs). The same is true for the female eggs. When a sperm and an egg combine they once again form a perfect cell with 46 chromosomes in 23 pairs. This one cell now has all the information (DNA) necessary to produce a complete human being. The combined DNA now has all the information of the physical characteristics of both parents. * Nafly Hussain*
