During Metaphase I, what happens to the homologous chromosome pairs?

Explanation:
In Metaphase I, homologous chromosome pairs line up along the cell’s middle (the metaphase plate) as paired units. Each chromosome, now composed of two sister chromatids, is held in place by kinetochores at the centromeres that attach to spindle fibers from opposite poles. This arrangement makes sure that, as the cell moves into Anaphase I, the homologs are pulled to opposite poles while the sister chromatids stay together. This differs from what happens in mitosis and from later stages, where sister chromatids separate or the nucleus reforms.
