gamete
Biology term for a mature haploid reproductive cell (sperm or egg) that fuses during fertilization.
Gametes are formed through meiosis.
During fertilization, the male and female gametes fuse.
Composed of 配偶 (haigū, 'mating, pairing') and 子 (shi, 'child, small unit'), literally 'mating cell'. The term is a modern biological coinage.
