Because, the chromosome set isn't complete
Join together (fuse)
It is the nulei which fuse. Nuclei are positively charged and thus repel each other. The kinetic energy of the nuclei must be very large for nuclei to be able to fuse, such as at the surface of the sun, where hydrogen nuclei fuse to form helium nuclei.
nuclear energy
A substance whose nuclei do not stay together
Basically because both nuclei are positively charged so repel each other.

Fertilization of sperm-nuclei.
fertilization
Fertilization
This is called FERTILIZATION. It means that the specific sperm cell that would later become a child, when the nuclei of the egg and sperm cell, joins with the egg. The fetus will begin to form when the nuclei of the two cells join, however it may take a while until the fertilization is complete.
