What is the purpose of cell division in mitosis?

• The purpose of cell division in mitosis is to produce two daughter cells that are genetically identical to the parent cell.

• The purpose of cell division in mitosis is to create genetically diverse daughter cells

• The purpose of cell division in mitosis is to increase the size of the cell

• The purpose of cell division in mitosis is to reduce the number of chromosomes in the cell

During which stage of meiosis do homologous chromosomes pair up?

• Metaphase I

• Anaphase I

• Telophase I

Compare the number of daughter cells produced in mitosis and meiosis.

• Mitosis produces more daughter cells (4) compared to meiosis (2).

• Mitosis and meiosis produce the same number of daughter cells.

• Meiosis produces more daughter cells (4) compared to mitosis (2).

• Mitosis produces 3 daughter cells while meiosis produces 2.

Explain how crossing over contributes to genetic diversity in meiosis.

• Crossing over contributes to genetic diversity in meiosis by preventing the exchange of genetic material.

• Crossing over contributes to genetic diversity in meiosis by creating new combinations of alleles on chromosomes.

• Crossing over contributes to genetic diversity in meiosis by duplicating the genetic material.

• Crossing over contributes to genetic diversity in meiosis by reducing the number of chromosomes.
