Life begins when the egg cell and sperm cell unite to form the zygote.
The zygote is the first cellular form of development in mammals. This results from the union of the sperm and egg cell.
Single birth occurs when one fertilized egg implants in the uterus and develops into a single fetus. This fertilization can result from the union of a sperm and egg during sexual intercourse. The fetus then goes through normal gestation until delivery as a single baby.
Neither. The union of a sperm and egg is called fertilization. Both sperm and egg cells are sex cells that are produced through meiosis.
The union of an egg and sperm restores the chromosome number through the process of fertilization. During fertilization, the haploid egg and haploid sperm fuse to form a diploid zygote, which contains the full complement of chromosomes (46 in humans). This restores the normal chromosome number in the resulting offspring.
Every human being begins life as a single cell known as a zygote, formed through the union of an egg cell and a sperm cell during fertilization.

Once a sperm enters the egg, fertilisation of the egg begins.

If you are fertile during the time you had sex. The sperm and egg had union and fertilized. Then you get pregnant. The egg will die like 3 days if it did not come into contact with a motile sperm.
