Picturing Mitosis And Meiosis

  1. 1. Do Now: compare these two, how are they similar? How are they different?
  2. 2. Picturing Mitosis and Meiosis Mr. Lin 2.6.08
  3. 3. Mitosis Steps <ul><li>Parent cell (duplicates / copies / replicates) its DNA </li></ul><ul><li>Cell divides into 2, DNA is divided into 2 daughter cells </li></ul>
  4. 4. Mitosis <ul><li>Parent cell (duplicates / copies / replicates) its DNA </li></ul><ul><li>Cell divides into 2, DNA is divided into 2 daughter cells </li></ul>
  5. 5. Mitosis <ul><li>Parent cell (duplicates / copies / replicates) its DNA </li></ul><ul><li>Cell divides into 2, DNA is divided into 2 daughter cells </li></ul>
  6. 6. Mitosis <ul><li>Parent cell (duplicates / copies / replicates) its DNA </li></ul><ul><li>Cell divides into 2, DNA is divided into 2 daughter cells </li></ul>
  7. 7. Meiosis Steps <ul><li>Parent cell replicates its DNA </li></ul><ul><li>Cells and DNA divide into 2 cells. </li></ul><ul><li>Cells and DNA divide again for a total of 4 daughter cells. </li></ul>
  8. 8. Meiosis <ul><li>Parent cell replicates its DNA </li></ul><ul><li>Cells and DNA divide into 2 cells. </li></ul><ul><li>Cells and DNA divide again for a total of 4 total daughter cells. </li></ul>
  9. 9. Meiosis <ul><li>Parent cell replicates its DNA </li></ul><ul><li>Cells and DNA divide into 2 cells. </li></ul><ul><li>Cells and DNA divide again for a total of 4 total daughter cells. </li></ul>
  10. 10. Meiosis creates variation <ul><li>Crossing-Over </li></ul>
  11. 11. Meiosis creates variation <ul><li>Independent Assortment </li></ul>
  12. 12. 4 2 Number of daughter cells Lots! Crossing-over and independent sorting Little or None Variation ½ set of chromosomes X H T Full set of chromosomes XX HH TT Daughter cells end with 2 1 # of divisions Full set of chromosomes XX HH TT Full set of chromosomes XX HH TT Parents cells start with Meiosis Mitosis
