20. Which of the following best explains why meiosis results in greater genetic diversity than mitosis?
a. After meiosis, daughter cells are diploid and have twice as much genetic material, which can be
divided in many more possible combinations.
b. After meiosis, haploid daughter cells are fertilized, which doubles their number of chromosomes
and increases the number of possible genes.
c. During meiosis, chromosomes assort themselves independently of each other, which allows for
more different possible combinations of chromosomes.
d. During meiosis, more daughter cells are produced, which increases the likelihdod that fertilization
will occur
21. What happens to sister chromatid in meiosis II?
a. they duplicate
b. they separate
c. they remain together
d. they do not take part
22. Why is it important for the daughter cells to divide a second time in meiosis?
a. The second division switches parts of matching chromatids to increase genetic variation.
b. The second division forms four identical cells to ensure that all offspring have the same traits.
c. The second division sorts chromosomes into cells that are the same as the parent cells.
d. The second division forms haploid cells that can combine with other haploid cells during
fertilization
23. Multicellular organisms use mitosis for growth, development and
b. repair
c. growth
d. interphase
a. apoptosis
24. In single celled organism, mitosis is used for
c. growth
b. reproduction
d. repair
a development
25. Somatic cells are produced by while sex cells reproduce by
a. meiosis, mitosis
b. mitosis, mitosis
c. mitosis, meiosis
d. meiosis, meiosis
