Presentation Transcript

  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

  18. Compare & Contrast Mitosis & Meiosis (BE SPECIFIC) • Contrast:
