Question

Name the stage in meiosis when there are two cells each with sister chromatids aligned at the equator of the spindle.

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

Answer 1

Answer: (C)

Metaphase II

Meiosis is the characteristic division of reproductive cells. It is also called reduction division because the parent cell produces four daughter cells, each having half the number of chromosomes present in the parent cell. It involves two successive nuclear division occurring one after the other, viz., meiosis I and meiosis II. Meiosis II is an equational division like mitosis and takes place simultaneously, in both the nuclei in which chromosomes divide or duplicate to form four haploid nuclei. Metaphase II is a part of meiosis II where the spindle is completely formed and all chromosomes get arranged in the equatorial plane with centromeres attached to the spindle fibers.

So the correct option is 'Metaphase II'.
