2. In mitosis, sister chromatids are separated during ______, while sisters are separated in ______ of

meiosis.

(a) prophase; prophase I

(b) anaphase; anaphase I

(c) metaphase; metaphase I

3. During meiosis I, _____.

(b) the generation of new combinations of alleles on the same chromosome

(c) the transmission of equivalent genetic information from generation to generation

(d) the genetic contribution of two individual parents to each offspring

(e) all of the above

5. A diploid somatic ("body") cell has 2n=20 chromosomes. At the end of mitosis, each daughter cell

would have ______ chromosomes. At the end of meiosis I, each daughter cell would have ______

chromosomes. At the end of meiosis II, each daughter cell would have ______ chromosomes.

(a) 2n=20, 2n=20, 1n=10

(b) 2n=20, 2n=10, 1n=10

(c) 1n=10, 1n=10, 1n=10

(d) 2n=20, 2n=20, 1n=20

(e) 2n=20, 1n=10, 1n=10
