Mitosis, Meiosis, & Viruses Quiz

What is the significance of crossing over during meiosis?

• 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

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
