Mitosis and Meiosis Pre- Test
Name _____________________________
SC.912.L.16.17 Compare and contrast mitosis and meiosis and relate to the
processes of sexual and asexual reproduction and their consequences for genetic
variation.
1. Which of the following best compares the processes of mitosis and meiosis?
A. Mitosis involves one division cycle and results in diploid daughter cells, while
meiosis consists of two division cycles and results in haploid gametes.
B. Mitosis involves one division cycle and results in haploid gametes, while
meiosis consists of two division cycles and results in diploid daughter cells.
C. Mitosis involves two division cycles and results in diploid daughter cells,
while meiosis consists of one division cycle and results in haploid gametes.
D. Mitosis involves two division cycles and results in haploid gametes, while
meiosis consists of one division cycle and results in diploid daughter cells.
2. Mitosis and meiosis are processes involved in cellular reproduction. Which of the
following describes an event that results from mitosis but NOT meiosis?
A. two stages of cell division
B. replication of cellular genetic material
C. daughter cells that are identical to the parent cell
D. four daughter cells that are produced from each parent cell
3. Which type of reproduction leads to increased genetic variation in a population?
A. parthenogenesis
B. asexual reproduction
C. sexual reproduction
D. vegetative reproduction
4. Which row in the chart below indicates the correct process for each event
indicated?
A. row 1
B. row 2
C. row 3
D. row 4
5. 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
likelihood that fertilization will occur.
SC.912.L.16.16 Describe the process of meiosis, including independent assortment
and crossing over. Explain how reduction division results in the formation of
haploid gametes or spore
6. 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.
7. The diagram below shows a cellular process that occurs in organisms.
What is the name of this process?
A. meiosis
B. mitosis
C. endocytosis
D. phagocytosis
8. What happens to sister chromatids in meiosis II?
A. They duplicate.
B. They separate.
C. They remain together.
D. They do not take part.
9. Which of the following cell types is diploid?
A. ovum
B. sex cell
C. somatic cell
D. gamete
10. The diagram below shows homologous chromosomes during prophase I of
meiosis.
Which of the following correctly describes the process being illustrated?
A. mutation in which the DNA content of the gene is altered
B. segregation of sister chromatids
C. condensation and segregation of alleles
D. crossing-over in which alleles are exchanged
11. Which of the following best describes how the process of crossing over during
meiosis leads to an increase in genetic diversity?
A. During prophase I, DNA replication takes place and homologous
chromosomes trade places with each other before lining up in preparation
for metaphase.
B. During prophase I, DNA segments are exchanged between homologous
chromosomes resulting in different combinations of alleles.
C. During prophase II, fragments of DNA break off of chromosomes and
attach to the ends of other chromosomes, resulting in different gene
sequences.
D. During prophase II, sister chromatids separate from each other, and as
they travel to opposite ends of the cell, DNA segments of nearby
chromosomes are exchanged.
12. Which phrase best describes meiosis I?
A. duplication of paired chromosomes
B. fusion of sister chromatids
C. division of homologous chromosomes
D. creation of two diploid cells
