Mitosis v. Meiosis BIO 3c

A cell undergoes mitosis to produce two daughter cells. Which of the following is true about these daughter cells?

• They are genetically identical to each other and to the parent cell.

• They have half the number of chromosomes compared to the parent cell.

• They undergo a process called crossing over.

• They are genetically unique and have different chromosome numbers.

Meiosis results in the production of gametes. How does this process differ from mitosis?

• Meiosis produces two daughter cells, while mitosis produces four.

• Meiosis results in cells with half the chromosome number of the parent cell, while mitosis produces genetically identical cells.

• Meiosis occurs only in somatic cells, while mitosis occurs in gametes.

• Meiosis does not involve DNA replication.

A cell undergoes meiosis and produces four daughter cells. Which of the following is true about these daughter cells?

• They are genetically identical to each other and to the parent cell.

• They have half the number of chromosomes compared to the parent cell.

• They each contain two complete sets of chromosomes.

• They are diploid, like the parent cell.

What is the significance of crossing over that occurs during meiosis?

• It ensures that the chromosomes are evenly distributed to each daughter cell.

• It increases genetic variation by exchanging genetic material between homologous chromosomes.

• It helps to separate the homologous chromosomes into different cells.

• It occurs only during mitosis to maintain chromosome number.

A cell is observed to have two sets of chromosomes, one from the mother and one from the father. This is a feature of which process?

• Mitosis

• Meiosis

• Cytokinesis

• DNA replication

Which of the following best describes the main difference between anaphase in mitosis and anaphase I in meiosis?

• In anaphase of mitosis, sister chromatids are separated, while in anaphase I of meiosis, homologous chromosomes are separated.

• In anaphase of mitosis, homologous chromosomes are separated, while in anaphase I of meiosis, sister chromatids are separated.

• In both processes, sister chromatids are separated.

• There is no difference between anaphase of mitosis and anaphase I of meiosis.

During which phase of meiosis do homologous chromosomes align in pairs at the cell's equator?

• Prophase I

• Metaphase I

• Metaphase II

• Telophase II

A cell undergoes mitosis, and the resulting daughter cells are diploid. What does this mean about the chromosome number of the daughter cells compared to the parent cell?

• The daughter cells have the same chromosome number as the parent cell.

• The daughter cells have half the chromosome number of the parent cell.

• The daughter cells have double the chromosome number of the parent cell.

• The daughter cells have one-fourth the chromosome number of the parent cell.
