What happens during Anaphase II in meiosis?
Options
- AThe chromosomes split
- BThe nuclear envelope reappears
- CThe centromere of each chromosome splits and the sister chromatids move toward opposite poles
- DCytokinesis takes place
Correct answer
C. The centromere of each chromosome splits and the sister chromatids move toward opposite poles
Step-by-step solution
Prophase II: 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 (Figure 10.4). The chromosomes again become compact. 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 (Figure 10.4) of sister chromatids. It begins with the simultaneous s
