WebbProphase of meiosis I is the signature event of the meiotic process, since it is here that genetic recombination takes place. Prophase is complex and is subdivided into five … 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. … informal term for having no moneyWebbGizmo Warm-up On the SIMULATION pane of the Cell Division Gizmo™, check that the Cycle Length is set to 12 hours.
