Meiosis Quiz

What are the two main stages of meiosis?

• Anaphase I and Anaphase II

• Meiosis I and Meiosis II

• Mitosis I and Mitosis II

• Prophase and Telophase

What happens during prophase I of meiosis?

• The chromosomes line up in the center of the cell

• The nuclear envelope breaks down

• Homologous chromosomes pair up and exchange genetic material

• The cell divides into two daughter cells

What is the significance of crossing over during meiosis?

• No impact on genetic variation

• Causes mutations

• Genetic recombination and increased genetic diversity

• Decreased genetic diversity

Explain the events that occur during metaphase I of meiosis.

• The nuclear envelope breaks down

• The chromosomes replicate to form sister chromatids

• Homologous chromosomes line up at the metaphase plate and are attached to the spindle fibers at their centromeres.

• The cell divides into two daughter cells

Describe the process of anaphase I in meiosis.

• Sister chromatids separate and move to opposite poles of the cell.

• The cell divides into two daughter cells.

• The chromosomes replicate.

• Homologous chromosomes separate and move to opposite poles of the cell.

What is the difference between meiosis I and meiosis II?

• Separation of homologous chromosomes in meiosis I and separation of sister chromatids in meiosis II

• Pairing of homologous chromosomes in meiosis I and pairing of sister chromatids in meiosis II

• Meiosis I occurs in males and meiosis II occurs in females

• No difference between meiosis I and meiosis II

Explain the events that occur during prophase II of meiosis.

• The nuclear envelope reforms, the spindle apparatus disappears, and the chromosomes decondense.

• The nuclear envelope remains intact, the spindle apparatus dissolves, and the chromosomes decondense.

• The nuclear envelope breaks down, the spindle apparatus forms, and the chromosomes condense.

• The cell divides into two daughter cells, the spindle apparatus disappears, and the chromosomes replicate.

Describe the process of metaphase II in meiosis.

• The nuclear envelope breaks down

• Chromosomes replicate to form sister chromatids

• Chromosomes line up at the equatorial plate of the cell.

• Homologous chromosomes separate and move to opposite poles

What happens during anaphase II of meiosis?

• The homologous chromosomes pair up in the center of the cell

• The nuclear membrane breaks down

• The cell undergoes cytokinesis

• The sister chromatids separate and move towards opposite poles of the cell.

What is the end result of meiosis?

• One daughter cell with double the number of chromosomes

• Two daughter cells with the same number of chromosomes

• Eight daughter cells with the same number of chromosomes

• Four daughter cells with half the number of chromosomes
