Meiosis involves two rounds of chromosome segregation and thus undergoes prophase twice, resulting in prophase I and prophase II. Prophase I is the most complex phase in all of meiosis because homologous chromosomes must pair and exchange genetic information. Prophase II is very similar to mitotic prophase. Prophase I is divided into five phases: leptotene, zygotene, pachytene, diplotene, and diakinesis. … WebbCold and colchicine have no visible effect on the form or manner of prophase (figure 3).
