WebLet’s start with the transition from “gamete” to “zygote”. The zygote has twice the number of chromosomes found in each gamete. How is this achieved? Sexual reproduction involves the fusion of two cells. These cells are the gametes. “Gamete” is a generic term. An egg is a gamete and so is a sperm cell.

WebLike in plants it is the male gamete that needs to be transferred to the female gamete. The female gamete is fertilised and develops inside the mother's body so the reproductive systems of both males and females are highly adapted for this.

Sexual life cycles involve an alternation between meiosis and fertilization. Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote.
