Remember that meiosis is the formation of gametes from germ cells. Our bodies begin the process of making germ cells very early in our development, and the precursors to sperm/egg cells are in tact well before puberty. When a woman ovulates, at the end, four of these egg cells complete the maturity stage in each cycle, but only one survives to become an ovulated egg (accompanied by 3 polar bodies). This egg (and its complement sperm) have ONE set of chromosomes each, and upon fertilization, the zygote will have 2 copies of every chromosome, one from the sperm, and one from the egg.
