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

Options

  1. ATelophase
  2. BMetaphase I
  3. CMetaphase II
  4. DAnaphase II

Correct answer

D. Anaphase II

Step-by-step solution

During the anaphase-I of meiosis-I, there is separation of homologous chromosomes to the forming daughter cells. However, the centromere division does not take place at this stage. During anaphase-II or meiosis II, there is splitting of the centromere. Basically, anaphase-II begins with the simultaneous splitting of the centromere of each chromosome (which holds the sister chromatids together), allowing them to move towards opposite poles of the cell by shortening of microtubules attached to kinetochores.
