Which of the following are CORRECT observations about the differences between 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.
