This cell depletion will continue throughout the female's life. By menarche there are only 500,000 eggs available to continue this monthly cycle for the next five decades until menopause.

Why do babies have redundancy?

One major reason for this is that females have a “spare X chromosome.” Essentially, this results in redundancy that protects against certain recessive defects caused by genes on the X chromosome. For example, if a male baby is born with the gene for red–green color blindness on its X chromosome, the boy will have red-green color blindness. However, a female baby needs to have the red-green color blindness gene on both of its X chromosomes, which is much less likely to occur.
