Which of the following is the best definition for MEIOSIS?

• the process of two haploid cells uniting

• the counting of chromosomes within a diploid cell

• a two-step process that reduces the number of chromosomes in half such that there is only one copy of all the chromosomes

• the equational division of a cell into two identical copies

True or False? Before cells undergo meiosis they pass through interphase first.

• true

• false

How many cells are formed at the end of Meiosis II?

• 2

• 3

• 4

• 8

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.
