Question

At what phase of meiosis are there two cells, each with sister chromatids aligned at the spindle equator?

• A. Anaphase II
• B. Metaphase II
• C. Metaphase I
• D. Anaphase I

Answer 1

The correct option is B Metaphase II

• Chromosomes are arranged at the spindle equator during the metaphase stage.
• During metaphase I, the homologous chromosomes are paired so that bivalents are arranged at the equator.
• These bivalents are comprised of four chromatids, these bivalents are present in a single cell.
• Meiosis I produces two haploid cells which undergo meiosis II.
• In metaphase II of meiosis II, the sister chromatids aligned at the equator of the cell.
• Thus, the correct answer is (B).
