Comparing Mitosis and Meiosis
Slide 001

2. Memory Maker! Mitosis Meiosis Makes my “toes” Makes a new “me”
Slide 002

3. Overall goal! Mitosis Meiosis
Produce identical cells with the same amount of DNA, to replace dying cells or allow growth.
Meiosis
Produce cells with ½ the original amount of DNA so that offspring can receive traits from each parent.
Slide 002

4. Cells That it Occurs in! Mitosis BODY CELLS Meiosis REPRODUCTIVE CELLS
(One cell divides once, resulting in two cells)
Meiosis
REPRODUCTIVE CELLS
(One cell divides twice, resulting in 4 cells)
Slide 002

5. Effect on DNA! Mitosis Meiosis Amount of DNA is cut in ½.
Amount of DNA is the same.
(Ex: Original Cell = 46 Chromosomes
Daughter Cell = 46 Chromosomes)
Meiosis
Amount of DNA is cut in ½.
(Ex: Original Cell = 46 Chromosomes
Daughter Cells = 23 Chromosomes)

6. Interphase – INCREASE! Grab 3 colors – don’t draw until Prophase!
Mitosis
Meiosis
BOTH CELLS BEGIN WITH 3 DIFFERENT CHROMOSOMES

7. Prophase – PAIRS! Grab 3 colors
Mitosis
Meiosis X X X X X X X X X X X X
BOTH CELLS BEGIN WITH 3 DIFFERENT CHROMOSOMES
