... Once the sperm penetrates the egg, the two nuclei fuse to become one, with 23 chromosomes from the father and 23 chromosome from the mother. A zygote is the single cell formed from the fusing of the sperm and ovum. After four days there are about 100 cells and it is now called a blastocyst. The orga ...
