During which phase of meiosis do homologous chromosomes cross over?

• Prophase I

• Metaphase I

• Anaphase I

• Telophase I

What are the similarities between meiosis and mitosis?

• Both involve cell division

• Both consist of similar phases

• Both require DNA replication previous to cell division

• Both divide into haploid cells

What are the differences between meiosis and mitosis?

• Mitosis only occurs in somatic cells, while meiosis occurs in gametes.

• Mitosis involves 5 phases while meiosis involves 9

• In meiosis there is genetic diversity in the daughter cells, while in mitosis there is not.

• Mitosis divides into diploid cells, while meiosis into haploid cells
