After meiosis II, which of the following is true about the cells that are produced?

• Four cells are produced. They are identical to each other and each contains half the number of chromosomes that the parent cell has.

• Four cells are produced. Each is unique and contains half the number of chromosomes that the parent cell has.

After meiosis I, which of the following is true about the cells that are produced?

• Two cells are produced. They are identical to each other and each contains half the number of chromosomes that the parent cell has.

• Two cells are produced. They are unique to each other and each contains half the number of chromosomes that the parent cell has.

• Four cells are produced. They are unique to each other and contain the same number of chromosomes that the parent cell has.

• Only one cell is produced. It is identical to the parent cell and contains the same number of chromosomes.

The four cells that are produced after Meiosis are _______.

• haploid because they contain just half the number of chromosomes as the parent cell.

• diploid because they contain as many chromosomes as the parent cell.

• diploid because they contain twice as many chromosomes as the parent cell.
