Solution
Both Statement I and Statement II are true.
Explanation:
Chromosomes progressively condense and become visible under a light microscope during the leptotene stage of meiosis. The synaptonemal complex, which keeps homologous chromosomes together, starts to break down during the diplotene stage. Diplotene begins with this disintegration. As a result, both claims are accurate in describing important meiotic prophase I events.
