How do the chromosomes become compact in meiosis II?

Step-by-step solution

Meiosis II is initiated immediately after cytokinesis, usually before the chromosomes have fully elongated. In contrast to meiosis I, meiosis II resembles a normal mitosis. The nuclear membrane disappears by the end of prophase II The chromosomes again become compact. The chromosomes become compact again in meiosis II by elongating, in contrast to meiosis I. Metaphase II: At this stage the chromosomes align at the equator and the microtubules from opposite poles of the spindle get attached to the kinetochores of si
