    Small correction to the comment above - a sperm doesn't have two of anything -- just one each of chromosomes 1-22 plus an X or a Y. For a total of 23. So does the egg, except it always has an X. When the two get together, you get 46 -- a pair of 1-22 plus XX or XY, depending on what the sperm brings to the occasion. Kudos to all - great site!

    Cool site, but a sperm only contains one (for a boy) or two (for a girl) X chromosomes, not 23...
