Question 1

Comparing and contrasting sexual and asexual reproduction.

Answer 1

Asexual reproduction generates offspring that are genetically identical to a single parent. In sexual reproduction, two parents contribute genetic information to produce unique offspring.

Question 2

Explaining how genetic variation can occur in asexual reproduction vs sexual reproduction.

Answer 2

Asexual reproduction generates offspring that are genetically identical to a single parent. In sexual reproduction, two parents contribute genetic information to produce unique offspring.

Question 3

Comparing and contrasting prophase of mitosis with prophase I and II of meiosis

Answer 3

Pairing of homologous chromosomes does not occur in the prophase of mitosis, whereas homologous chromosomes pair up in prophase I of meiosis I. In the prophase of mitosis, recombination, and crossing over do not take place. In prophase, I of meiosis I, recombination, crossing over, and synapsis takes place.

Question 4

Comparing and contrasting anaphase of mitosis with anaphase I and II of anaphase

Answer 4

Anaphase I separates homologous chromosomes, while Anaphase II separates sister chromatids.

Question 5

Comparing and contrasting parent and daughter cells of mitosis and meiosis

Answer 5

Mitosis produces two genetically identical “daughter” cells from a single “parent” cell, whereas meiosis produces cells that are genetically unique from the parent and contain only half as much DNA.
