Question

Meiosis II resembles mitosis except that:

• A. Unlike that of mitosis, anaphase II of meiosis II does not involve separation of sister chromatids
• B. Unlike that of mitosis, telophase II of meiosis II does not involve cytokinesis
• C. Unlike that of mitosis, metaphase II of meiosis II does not involve alignment of the chromosomes on the equator of the cell
• D. Unlike that of mitosis, prophase II of meiosis II is not preceded by doubling of DNA content

Answer 1

The correct option is D Unlike that of mitosis, prophase II of meiosis II is not preceded by doubling of DNA content

Mitosis is an equational cell division in which a diploid parent cell divides to give rise to two diploid daughter cells.
Meiosis II is also an equational division in which haploid parent cells divide to give rise to haploid daughter cells. Hence, meiosis II resembles mitosis. The main difference between meiosis II and mitosis is that while mitosis is preceded by a round of DNA replication, meiosis II is not preceded by DNA replication.
The subsequent steps of meiosis II (prophase II, metaphase II, anaphase II and telophase II) resemble the steps of mitosis.
