The name of the cell formed by the fusion of a sperm and an egg.

Use in clinical context

A zygote is formed at fertilisation when a sperm and egg fuse. This cell then divides to form an embryo and ultimately a foetus. Any genetic variants in the zygote will be passed on to all subsequent daughter cells and so will be present in all cells in the individual.
