Biology · CELL CYCLE AND CELL DIVISION

How does Metaphase I of meiosis differ fundamentally from Metaphase II?

1. In Metaphase I, bivalent chromosomes align in two parallel rows at the equator, whereas in Metaphase II individual chromosomes align singly at the equator
2. Centromeres split in Metaphase I but remain intact in Metaphase II
3. Spindle fibres attach to both sister chromatids of a chromosome from opposite poles in Metaphase I
4. DNA replication takes place immediately prior to Metaphase II but not before Metaphase I
