Now, the process of fertilization has two important functions. Firstly, what it does is it restores the deployed number of chromosomes of that particular organ organism. In the case of the human organism, we have 23 chromosomes that are found in the sperm cell, in the nucleus of the sperm cell, and this is a haploid number. Likewise, the egg that came from the female parent contains 23 chromosomes, a haploid number in the nucleus. And when these two cells, the sperm and our egg, fuse, the number of chromosomes is restored. 23 plus 23 gives us 46, a deployed number of chromosomes.
