Q. Meiosis II resembles mitosis except that:

1. Unlike that of mitosis, prophase II of meiosis II is not preceded by doubling of DNA content
2. Unlike that of mitosis, anaphase II of meiosis II does not involve separation of sister chromatids
3. Unlike that of mitosis, telophase II of meiosis II does not involve cytokinesis
4. Unlike that of mitosis, metaphase II of meiosis II does not involve alignment of the chromosomes on the equator of the cell
