Meiosis

• Cells in reproductive organs divide by meiosis to form gametes (egg and sperm cells)
• When a cell divides to form gametes: • copies of the genetic information are made • the cell divides twice to form four gametes, each with a single set of chromosomes • all gametes are genetically different from each other
• Gametes join at fertilisation to make a new cell with the normal number of chromosomes. The new cell divides by mitosis to grow
