Which of the following stages of meiosis involves division of centromere ?

The correct option is Anaphase II.

To understand why centromere division occurs during Anaphase II, let us break down the stages of cell division in meiosis:

1. Meiosis I vs. Meiosis II:
Meiosis is a specialized form of cell division consisting of two rounds of division: Meiosis I and Meiosis II. While Meiosis I is responsible for separating homologous chromosome pairs, Meiosis II is responsible for separating sister chromatids.

2. Behavior of Centromeres during Anaphase I:
During Anaphase I, homologous chromosomes are pulled apart to opposite poles. Crucially, the sister chromatids of each chromosome remain joined together at their centromeres. Consequently, no division of centromeres occurs in this stage.

3. Behavior of Centromeres during Anaphase II:
During Anaphase II, chromosomes align at the metaphase plate (during Metaphase II), and spindle fibers attach to the kinetochores of sister chromatids. In Anaphase II, the centromere holding the sister chromatids together finally divides, allowing them to separate. Once separated, they are considered individual chromosomes and are pulled toward opposite poles of the cell.

Therefore, the division of centromeres takes place during Anaphase II.
