a zygote is form when an egg and sperm fuses togerther .
They form from the merger of two haploid (half-gened cells: a sperm and an egg). Actually in mammals the egg swallows the sperm, and the nuclear material fuses together.
Semen or sperm
It fuses with the membrane of the egg cell, and the content of the sperm cell enters the egg cell.
When sperm fuses with egg it is called fertilization .
When sperm fuses with egg it is called fertilization .
The very first result of egg and sperm coming together is a zygote. This will begin to divide many, many times to finally form an individual.

The very first result of egg and sperm coming together is a zygote. This will begin to divide many, many times to finally form an individual.
First, a sperm identifies an egg, sticks to its jelly-like coating and strips to reveal parts of its cell membrane. In the second phase, the cell membranes of the egg and sperm cling together in an intimate embrace, before fusing to allow the DNA to meet.
Fetilization. Results in a zygote.
When a sperm fuses with an egg in fertilization, the resulting zygote nucleus receives two complete sets of chromosomes, one set from the egg and one from the sperm.
The nuclei of the egg and sperm cells fuse to form the fertilized egg.
