Meiosis

• meiosis only takes place in reproductive organs (testes,ovaries)
• Meiosis splits the number of chromosomes and makes 4 gametes from one original cell and are GENETICALLY DIFFERENT because each gamete has different alleles
• Two gametes with half the amount if chromosomes (23)(from meiosis) fertilise and now has the normal number of chromosomes (46)
• Stage 1 - all chromosomes are copied

  stage 2 - cell divides into two

  stage 3 - both these cells split and divide one more time forming gametes ( in this gamete chromosomes are single (23) and NOT PAIRED yet)
