Meiosis Worksheet
Identifying Processes On the lines provided, order the different stages of meiosis I THROUGH meiosis II, including
interphase in the proper sequence.
1. _____________ homologous chromosome lines up in the center of the cell
2.______________ spindle fibers pull homologous pairs to ends of the cell
3. _____________ 4 haploid (N) daughter cells form
4. _____________ cells undergo a round of DNA replication
5.______________ sister chromatids separate from each other
6. _____________ 2 haploid (N) daughter cells form
7.______________ spindle fibers attach to the homologous chromosome pairs
8. _____________ individual chromatids move to each end of the cell
9.______________ crossing-over (if any) occurs
Short Answer
10. Compare the number and type of cells that result from meiosis vs. mitosis.
11. How do the genetic contents of cells resulting from mitosis and meiosis differ?
12. Comparing and Contrasting Describe a similarity and a difference between meiosis I and meiosis II.
13 Applying Concepts If a diploid cell containing 28 chromosomes undergoes meiosis, how many chromosomes will each
daughter cell have?
14 Compare and Contrast: How are mitosis and meiosis similar and different?
Read each statement, and then on the line write down the phase of mitosis or meiosis that the action occurs. IF the
action occurs in both, write both. The first one is done for you
1. metaphase I meiosis ___________________ homologous chromosome line up in the center of the cell
2 ________________________________________ The individual chromosomes move apart.
3.________________________________________ spindle fibers pull homologous pairs to ends of the cell
4. _______________________________________ 4 haploid (N) daughter cells form
5. _______________________________________ cells undergo a round of DNA replication
6. _______________________________________ The chromosomes line up across the middle of the cell.
7. _______________________________________ Chromosomes become visible.
8.________________________________________ sister chromatids separate from each other
9. _______________________________________ 2 haploid (N) daughter cells form
10. ______________________________________ Sister chromatids separate into individual chromosomes.
11. ______________________________________ Nuclear envelope re-forms.
12._______________________________________ spindle fibers attach to the homologous chromosome pairs
13. ______________________________________ individual chromatids move to each end of the cell
14. ______________________________________ The nucleolus disappears and the nuclear envelope beaks down.
15. ______________________________________ Each chromosome is connected to a spindle fiber.
16._______________________________________ crossing-over (if any) occurs
Name of Phase

Description
Homologous chromosomes pair up and form a
tretrad
Spindle fibers move homologous chromosomes
to opposite sides
Nuclear membrane reforms, cytoplasm divides, 4
daughter cells forms
Chromosomes line up along equator, not in
homologous pairs
Crossing over occurs
6.
Chromatids separate
7.
Homologs line up along equato
8.
Cytoplasm divides, 2 daughter cells are formed

2. Mitosis v. Meiosis-Explaining Differences: Explain what happens in each of the following processes in
Meiosis that is different from Mitosis and why the difference is important.
Prophase I (in Meiosis I):
Metaphase I and Anaphase I (in Meiosis I):
Meiosis II:
Draw the chromosomes in the cell as it undergoes mitosis.
Draw the chromosomes in the cell as it undergoes meiosis.
