Multiple Choice

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

• 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 their 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.

Multiple Choice

Meiosis is a life process associated with sexual reproduction. Which choice correctly summarizes meiosis into one statement?

• Haploid cells join and produce diploid daughter cells.

• Chromosomes in a haploid cell are pulled apart, creating two haploid daughter cells.

• Chromosomes in a diploid cell uncoil and line up, creating two diploid daughter cells.

• Homologous chromosomes in a diploid cell separate and produce four haploid daughter cells.

Multiple Choice

Multiple Choice

How are sexual reproduction and asexual reproduction different?

• Sexual reproduction produces offspring identical to the parents, but asexual reproduction produces offspring with traits from both parents.

• Asexual reproduction produces offspring identical to the parents, but sexual reproduction produces offspring with traits from both parents.

• Sexual reproduction only occurs in multicellular organisms, but asexual reproduction only occurs in unicellular organisms.

• Asexual reproduction only occurs in multicellular organisms, but sexual reproduction only occurs in unicellular organisms.

Multiple Choice

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

• 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.

Multiple Choice

Some organisms are able to reproduce asexually through mitosis, while cells of organisms that reproduce sexually will undergo meiosis to produce gametes. Which process do you predict would be most beneficial to a species during drastic change in environmental conditions?

• Meiosis; it results in more daughter cells, which increases the population of the species.

• Meiosis; it results in more genetic variation, which would help ensure the species will survive.

• Mitosis; it results in more genetic mutations, which may be advantageous to the species.

• Mitosis; it results in more offspring in a short time, which increases the odds that some will survive.

Multiple Choice

Cells and the organisms they make up reproduce through cell division. Some organisms reproduce through mitosis, while others reproduce through meiosis and fertilization. What advantage does meiosis give to organisms that reproduce sexually?

• Meiosis ensures that offspring inherit genes from their parents.

• Meiosis ensures that offspring will not inherit any genetic disorders.

• Meiosis ensures that offspring are genetically different from their parents.

• Meiosis ensures that offspring will have identical phenotypes to their parents.
