Sexual reproduction involves the production of sex cells, known as gametes, which are made in reproductive organs called testes (in males) and ovaries (in females).
The process of cell division that produces the gametes is called meiosis.
In sexual reproduction, the male and female gametes come together and fuse, joining their cytoplasm and nuclei to form a single cell called a zygote.
The zygote or embryo then grows into a new individual.
