Web1) Prophase I is the finest time to watch chiasmata develop during meiosis. This is due to the fact that chiasmata are created during the crossing over process, which takes place during prophase I of meiosis. In this phase, homologous chromosomes join up and cross over to exchange genetic material, leading to the development of chiasmata.
