meiosis

• gametes are produced by Meiosis
• meiosis produces cells with half the normal number of chromosomes
• what is the process of meiosis?

  1. duplicates genetic information, forming 2 armed chromosomes
  2. first division - the chromosome pairs line up in the centre of the cell
  3. the pairs are pulled apart with some of the fathers and mothers chromosomes in each new cell
  4. second division - the chromosomes line up again and the arms are pulled apart
  5. you get 4 gametes each with one a single set of chromosomes in it
