Mature haploid cells that fuse to form a zygote in sexual reproduction. In many organisms, the male gamete is called a spermatozoon, spermatozoid or antherozoid. The female gamete is referred to as an ovum. As haploid cells, they contain half the normal complement of chromosomes and thus when they fuse the diploid number is restored. Gametes are formed by meiosis.
