26

23

46

43

1

If a eukaryotic cell has 20 chromosomes and it undergoes meiosis, how many cells will result, and how many chromosomes will they contain?

2 cells, each with 20 chromosomes

4 cells, each with 10 chromosomes

4 cells, each with 20 chromosomes

2 cells, each with 10 chromosomes

1

Cells that are ________ possess a single set of chromosomes

zygotes

somatic

haploid

diploid

1

You have homologous pairs of chromosomes in each of your cells. In what way are these pairs of chromosomes similar?

They have exactly the same genes.

They will stay together during meiosis

They both come from the same parent

They have genes for the same traits

1

From the list below, which choice represents a correct difference between sperm production and egg production?

Sperm are produced by mitosis; eggs are produced by meiosis

Sperm are produced by meiosis; eggs are produced by mitosis.

Four mature sperm are produced from one cell; one large egg is produced from one cell.

Eight mature sperm are produced from one cell; two eggs are produced from one cell

Sperm are produced by somatic (body) cells; eggs are produced by gametes

1

Sister chromatids inside both cells get separated during this phase

1

Tetrads line up along the equator during this phase

1

At the end of meiosis I, the daughter cells created are DIPLOID or HAPLOID?

1

Meiosis occurs in what type of cells

Short Answer: Answer the questions below using sentences or bullets.

5

Why does meiosis have two cell divisions? (HINT: Think of chromosome number) Why is this important for reproduction?

5

Explain why the daughter cells produced by meiosis are genetically different from each other, whereas the daughter cells produced by mitosis are not.

2

What two major events occur during meiosis that give the new cells genetic variation?

2

Though the stages of meiosis have the same names as the stages of mitosis, they exhibit fundamental differences. What are the main differences between the two processes?

Prophase and telophase portions of meiosis and mitosis are the same. Meiosis II and mitosis are also the same and have the same number of chromosomes. Anaphase I and anaphase are different.

Metaphase and telophase portions of meiosis and mitosis are the same. Meiosis and mitosis are also the same, except for the number of chromosomes. Anaphase I and anaphase are different.

Meiosis differs from mitosis in that the number of chromosomes is halved and genetic variation is reduced in meiosis, but not in mitosis.

Meiosis differs from mitosis in that the number of chromosomes is halved and genetic variation is introduced in meiosis, but not in mitosis
