1. Meiosis It’s all about the Chromosomes

3. Why do Mitosis and Meiosis?
Meiosis makes gametes and plant spores
Meiosis only happens in reproductive cells

4. In the beginning there is Interphase

5. Draw and label on pg 6

6. Stages (pg 6)
Meiosis I = Prophase I, Metaphase I, Anaphase I and Telophase I
Cytokinesis
Meiosis II = Prophase II, Metaphase II, Anaphase II and Telophase II

7. Meiosis I (pg6) Prophase I = DNA forms chromosomes
Metaphase I = chromosomes line up in homologous pairs

8. Count the centromeres
Number Chromosomes = number centromere

9. Meiosis I cont. Anaphase I = homologous chromosomes get pulled apart
Telophase I = Nuclear membranes form and cytoplasm divides

10. Keep 46 Chromosomes in each cell in Meiosis I

11. Meiosis II Start with 2 daughter cells with 46 chromosomes
Prophase II = membrane dissolves
Metaphase II = chromosomes line up in middle

12. Meiosis II cont. Anaphase II = split and move to opposite sides
Telophase II = nuclear membrane forms

13. End Meiosis with 4 daughter cells with 23 chromosomes

14. Steps of Meiosis

15. Compare and Contrast Mitosis and Meiosis
