WebGametes are reproductive cells. Male gametes are called sperm. Female gametes are called ova. Fertilisation takes place in the oviduct when the nucleus of a sperm fuses … WebAsked By : Joseph Anderson. Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.
