1. Meiosis

2. Identify the stage

3. What stage?

4. Review homologs = matching chromosomes gene = alleles =

5. Key Vocabulary somatic cell –  gamete -  example gonad -

6. Key Vocab (cont) diploid (2n) – haploid (n) – Which is diploid, a somatic cell or a gamete?

7. Purpose of Meiosis  to produce gametes! (That’s easy!) OR  to reduce # chromosomes per cell by ½ WHY?? (See board)

8. What is a tetrad?

9. What funky thing do tetrads do?

10. Stages of Meiosis:

11. Interphase

12. Prophase I Is this cell human? How many chromosomes are pictured? How many pairs of chromosomes How many tetrads? What is 2n for this organism?

13. Metaphase I Note tetrads (pairs) line up on equator instead of duplicated chromosomes

14. Anaphase I

15. Telophase I How many cells? How many chromosomes per cell? How many pairs of chromosomes in each cell?

16. Prophase & Metaphase II

17. Anaphase & Telophase II
