organs divide by meiosis to form gametes. When a cell divides to form gametes: copies of the genetic information are made and the cell divides twice to form four gametes, each with a single set of chromosomes.

The new cell divides by mitosis, and as the embryo develops cells differentiate. Explain why sexual reproduction results in variety. Draw diagrams to explain how gametes are formed in meiosis. Explain the number of chromosomes in the gametes during meiosis and fertilisation. Describe how an embryo is formed.
