A36 (4.6) Copies of the genetic material are made and then the cell divides into two identical cells. It is needed for growth or repair of cells. A41 (4.6) A small section of DNA. A40 (4.6) Because each gamete is different and when they fuse with another gamete this leads to variety A39 (4.6) Using Meiosis. They only contain one set of chromosomes.
