When sperm and egg come together

To become pregnant , sperm from a male has to meet an egg from a female. This can happen when a male and female have sexual intercourse, when the penis is in the vagina. If an egg has been released and is in the fallopian tube, one of these sperm may reach the membrane of the egg and get inside it. This process is called fertilisation. DNA, or genetic material, from the egg and sperm meet and join together. All babies get half their genes from their mothers and half from their fathers.

NCBI Bookshelf. Molecular Biology of the Cell. New York: Garland Science; Once released, egg and sperm alike are destined to die within minutes or hours unless they find each other and fuse in the process of fertilization. Through fertilization , the egg and sperm are saved: the egg is activated to begin its developmental program, and the haploid nuclei of the two gametes come together to form the genome of a new diploid organism.
