The process where sex cells fuse is called fertilization. During fertilization, a sperm cell from a male merges with an egg cell from a female, resulting in the formation of a zygote. This zygote contains a complete set of chromosomes, half from each parent, and begins to divide and develop into an embryo. Fertilization can occur internally or externally, depending on the species.
