The fusing of sperm and an ovum is the initial stage in the reproductive process. One of the sperms may fuse with the egg when sperms come into touch with an egg. Fertilisation is the process of the egg and sperm fusing together. The nuclei of the sperm and the egg fuse together during fertilisation to form a single nucleus. A fertilised egg, also known as a zygote, is formed as a result of this process. The meeting of a female's egg cell and a male's sperm cell is known as fertilisation. As a result, the new individual receives some traits from the mother and some from the father. Internal fertilisation is the process of fertilisation that takes place inside the female body.
