Unformatted text preview: Modeling Meiosis 1. Take your chromosomes through the S phase of the cell cycle and prepare them for meiosis . 2. Arrange each homologous pair in synapsis . 3. Use pipe cleaner pieces to connect the sister chromatids at the centromere. 4. Take your chromosomes through all the stages of meiosis and find out how many different kids of gametes can be formed. What is the haploid number of this organism (n)? 5. Join another group and restore the diploid number with sexual reproduction. Modeling Crossing Over 1. Put your chromosomes back in synapsis. 2. Model crossing over with two pop beads between two sister chromatids of homologous pairs. 3. Take your chromosomes through all the stages of meiosis again and find out how many different kids of gametes can be formed....
