Drill – April 1, 2010
1. Each laboratory group should obtain an envelope from the class manager.
2. Take out the meiosis cards and spread them out on their desk. The pictures show the steps of the process of
meiosis.
3. Put the pictures in order. When your group has the pictures in order, label each phase with a transparency
marker.
4. Finally, match the descriptions of each phase to the appropriate labeled picture.
5. Check your work with the teacher when you think that you have properly completed the task.
6. When instructed, place all materials back in the envelope.

Comparing Mitosis and Meiosis
Mitosis
Meiosis
One division occurs during mitosis.
Two sets of divisions occur during meiosis: meiosis I and
meiosis II.
DNA replication occurs during interphase
DNA replication occurs once before meiosis I.
Synapsis of homologous chromosomes does not
occur.
Synapsis of homologous chromosomes occurs during
prophase I.
Two identical cells are formed per cell cycle.
Four haploid cells (n) are formed per cell cycle.
The daughter cells are genetically identical.
The daughter cells are not genetically identical because of
crossing over.
Mitosis occurs only in body cells.
Meiosis occurs in reproductive cells.
Mitosis is involved in growth and repair.
Meiosis is involved in the production of gametes and
providing genetic variation in organisms.

Enjoy your Easter Break.
You may want to review Meiosis before you return on April 12th.
