IDENTIFICATION 1. Each single fuzzy piece (pipe cleaner) equals one chromosome (in interphase a single pink piece equals one chromosome originally inherited from the mother) (in interphase a single blue piece equals one chromosome originally inherited from the father).

Two fuzzy pieces, held together by a bead the bead represents the centromereequals one chromosome replicated into two strands (AKA: chromatids), (think “chromosome kids”) each of which becomes a separate chromosome when the centromere splits at the beginning of anaphase (mitosis) or anaphase II (meiosis).

Step 1. Arrange the pieces on the MITOSIS sheet, showing the essential chromosome arrangements during mitosis. • You won't need all the pieces for this part. When done, raise your hand to be checked. (if unsure, refer back to Chapter 10) Step 2. When your MITOSIS layout is approved, copy those arrangements onto your separate Mitosis. Meiosis Summary Sheet, using red and blue pencils (or using any 2 colors to represent the chromosomes).

APPLICATION Make sure to DRAW on your lab sheet the stages of mitosis and meiosis from your pipe cleaner model. • Be sure to use colored pencils to represent your two colors • ANSWER THE QUESTIONS: What are the 2 main functions of meiosis? 2 shown in this activity, and what are we not representing in prophase I of meiosis……? •

ASSUMPTIONS (for this lab): • Diploid number (2 N) of this organism is "4 chromosomes", or pair; • Haploid number (N) of the reproductive cells is “____ chromosomes” • In interphase you will show that the chromosomes have not, yet, replicated. • In prophase you will show that the chromosomes have already replicated. Twisting and crossing-over will NOT to be shown in this activity. DO NOT PULL THE CHROMOSOMES APART

• Step 3. Remove all pieces and proceed to arrange them on the two MEIOSIS sheets, with MEIOSIS I sheet placed above the MEIOSIS II sheet so the arrows flow from sheet to sheet. Remember to show the essential differences between mitosis and meiosis. • Be sure to end up with either sperm (if you are a boy), or an egg with polar bodies (if you are a girl). • You will use ALL of the pieces for meiosis. When finished, raise your hand to be checked by your teacher.

• Step 4. When your meiosis layout is approved, copy the arrangements onto your separate Mitosis - Meiosis Summary Sheet, using red and blue pencils (or using any 2 colors to represent chromosomes) • Step 5. Count all pieces and put them back into their container, and return the container and "layout" sheets to the tray. • Step 6. Now, help others by giving clues; do NOT show the correct arrangements; let others discover this as you did.
