And the xcel contains a haploid number 23 chromosomes that came from the female parent. And so once they fuse, the nuclei fuse as well. So 23 plus 23 and we form a diploid number, 46 chromosomes. So this is an important point to remember that our xcel actually remains in metaphase two until the fusion of the sperm cell and that XL takes place. And only during fertilization does our xcel finish meiosis. And only then do we actually, actually form that mature ovum, that mature ex cell.
