Meiosis Review

Match the following for mitosis and meiosis.

• Mitosis

• Sister Chromatids (already crossed over) pull apart

• Mitosis & Meiosis

• makes 2 identical cells

• Anaphase 2 of Meiosis

• PMAT happens once or twice

• Meiosis

• Homologous Chromosomes pulled apart & Independent assortment

• Anaphase 1 of Meiosis

• makes 4 genetically different cells

2 diploid (2n) daughter cells form in what phase of Meiosis?

• Telophase 2

• Telophase/Cytokinesis 1

• Anaphase 2

• Cytokinesis 2

Which of the following are CORRECT observations about MITOSIS and MEIOSIS? (Check all that apply.)

• Mitosis produces cells that identical to the parent cell.

• Meiosis produces cells that have half the number of chromosomes as the parent cell.

• All cells go through INTERPHASE as part of the cell cycle, whether it goes to mitosis or meiosis next.

• In both types of cell division, the chromosomes are only duplicated once.

• Only in Mitosis, do you see chromosomes pair up to form a tetrad.
