If an organism’s diploid number is 12, its haploid number is

• 6.
• 12.
• 24.
• 3.

Gametes are produced by the process of

• meiosis.
• mitosis.
• replication.
• crossing-over.

Unlike mitosis, meiosis results in the formation of

• 2N daughter cells.
• haploid cells.
• body cells.
• diploid cells.

Which of the following is a correct statement about the events of the cell cycle?

• DNA replicates during cytokinesis
• Little happens during the G1 and G2 phases
• Interphase consists of the G1, S, and G2 phases
• The M phase is usually the longest phase

The centromere is a region in which

• metaphase chromosomes become aligned at the metaphase plate.
• chromosomes are grouped during telophase.
• chromatids remain attached to one another until anaphase.
• the nucleus is located prior to mitosis.
