They are gametes that come together to form a zygote. They hold genetic information from each parent.

A sperm and an egg.
Neither. The union of a sperm and egg is called fertilization. Both sperm and egg cells are sex cells that are produced through meiosis.
All human gametes (sex cells), which means egg cells and sperm cells, have 23 chromosomes. When the sperm fertilises the egg, the 23 chromosomes from the egg cell and the 23 chromosomes from the sperm cell join to make cells with 46 chromosomes. In summary, all cells in the human body have 46 chromosomes, except sperm cells and egg cells, which have 23.
Sperm cells and egg cells named together are called gametes.
