• 8.

• 16.

• 32.

• 64.

How are the processes of mitosis and meiosis similar to each other?

• Both processes result in the same number of cells produced.

• Both processes involve only one division of cellular material.

• Both processes begin with similar events, including chromosome replication.

• Both processes end with the same number of chromosomes present in each cell.

What is the outcome when a cell undergoes meiosis?

• two diploid cells

• two haploid cells

• four diploid cells

• four haploid cells

Haploid cells are
