Meiosis EOC Review

What is a key difference between meiosis I and meiosis II?

• Meiosis I produces haploid cells, while meiosis II starts with diploid cells.

• Meiosis I separates homologous chromosomes, while meiosis II separates sister chromatids.

• Meiosis I duplicates DNA, while meiosis II does not.

• Meiosis I occurs in somatic cells, while meiosis II occurs in gametes.

What is the primary purpose of meiosis?

• To produce identical cells

• To repair damaged cells

• To produce gametes with half the number of chromosomes

• To duplicate the DNA content in a cell

During which phase of meiosis do homologous chromosomes separate?

• Prophase I

• Metaphase I

• Anaphase I

• Anaphase II
