Directions:

  1. Complete the illustrations that show the differences between mitosis and meiosis.
  2. Consider the two-winged fly species Cricotopus sylvestris with chromosome number 2n = 4.
  3. Draw the stages (prophase, metaphase, anaphase and telophase with cytokinesis) of the two cell divisions in the corresponding boxes of Table 1. No need to include prometaphase. One box is to one stage.
  4. For each stage, draw clearly the appearance and configuration of the cell(s) and the chromosomes. Inspect and refer to slides 10 to 11 of the Cell Division PPT for mitosis and slides 14 and 17 for meiosis. Make sure that when the pictures are zoomed in, they will still be clear.
  5. For better illustration, draw the chromosomes with different sizes (inspect and refer to slides 10 to 11 of the Cell Division PPT for mitosis and slides 14 and 17 for meiosis). Use one color for the chromosomes in mitosis and two colors for the chromosomes in meiosis (see slides 10 to 11 of the Cell Division PPT for mitosis and slides 14 and 17 for meiosis).
  6. For the description of each stage, include the following:
  • complete name of the stage (include correct number for those that need to have one)
  • unique and important events undergone by the cell(s) and chromosomes
  • appearance and configuration of the chromosomes (thinness or thickness, double-stranded or single-stranded, etc.)
  • number of chromosomes in each cell (whether 2n = __ or n = _ )
  • number of daughter cells (There are only 3 stages that should have this so most of the stages would have zero. Write the number zero then.)
