4. How does metaphase in meiosis I and meiosis II differ?

A.Sister chromatids are on the metaphase plate in meiosis I and tetrads are on the

metaphase plate in meiosis II.

B.Homologous chromosomes line up in meiosis I and duplicated chromosomes line up in

meiosis II.

C.All chromatids are the exact same in meiosis I and differ in meiosis II due to

independent assortment
