Mitosis and Meiosis

Question 1 of 10

1

Mitosis and meiosis are processes involved in cellular reproduction. Which of the following describes an event that results from mitosis but NOT meiosis?

Select one of the following:

Two stages of cell division
Replication of cellular genetic material
Daughter cells that are identical to the parent cell
Four daughter cells that are produced from each parent cell

Explanation

Question 2 of 10

1

Which type of reproduction leads to increased genetic variation in a population?

Select one of the following:

Parthenogenesis
Asexual reproduction
Sexual reproduction
Vegetative reproduction

Explanation

Question 3 of 10

1

Which of the following best compares the processes of mitosis and meiosis?

Select one of the following:

Mitosis involves one division cycle and results in diploid daughter cells, while meiosis consists of two division cycles and results in haploid gametes
Mitosis involves one division cycle and results in haploid gametes, while meiosis consists of two division cycles and results in diploid daughter cells
Mitosis involves two division cycles and results in diploid daughter cells, while meiosis consists of one division cycle and results in haploid gametes
Mitosis involves two division cycles and results in haploid gametes, while meiosis consists of one division cycle and results in diploid daughter cells

Explanation

Question 4 of 10

1

Which of the following best explains why meiosis results in greater genetic diversity than mitosis?

Select one of the following:

After meiosis, daughter cells are diploid and have twice as much genetic material, which can be divided in many more possible combinations
After meiosis, haploid daughter cells are fertilized, which doubles the number of chromosomes and increases the number of possible genes
During meiosis, chromosomes assort themselves independently of each other, which allows for more different possible combinations of chromosomes
During meiosis, more daughter cells are produced, which increases the likelihood that fertilization will occur

Explanation

Question 5 of 10

1

Which of the following occurs during mitosis?

Select one of the following:

The cell membrane pinches one cell into two
The chromosomes of the patient cell are copied
The parent cell takes in nutrients and doubles in size
The nucleus of the parent cell divides into two nuclei

Explanation

Question 6 of 10

1

In a single celled organism, mitosis is used for:

Select one of the following:

Development
Reproduction
Growth
Repair

Explanation

Question 7 of 10

1

Multicellular organisms use mitosis for growth, development and:

Select one of the following:

Apoptosis
Repair
Reproduction
Interphase

Explanation

Question 8 of 10

1

Why is it important for the daughter cells to divide a second time in meiosis?

Select one of the following:

The second division switches parts of matching chromatids to increase genetic variation
The second division forms four identical cells to ensure that all offspring have the same traits
The second division sorts chromosomes into cells that are the same as the parent cells
The second division forms haploid cells that can combine with other haploid cells during fertilization

Explanation

Question 9 of 10

1

What happens to sister chromatids in meiosis II?

Select one of the following:

They duplicate
They separate
They remain together
They do not take part

Explanation

Question 10 of 10

1

Which of the following describes how the process of crossing over during meiosis leads to an increase in genetic diversity?

Select one of the following:

During prophase I, DNA replication takes place and homologous chromosomes trade places with each other before lining up in preparation for metaphase
During prophase I, DNA segments are exchanged between homologous chromosomes resulting in different combinations of alleles
During prophase II, fragments of DNA break off of chromosomes and attach to the ends of other chromosomes, resulting in different gene sequences
During prophase II, sister chromatids separate from each other, and as they travel to oppsite ends of the cell, DNA segments of nearby chromosomes are exchanged
