Prophase may be divided into successive stages termed leptotene, zygotene, pachytene, diplotene, and diakinesis.

前可被分为连续的阶段：细、偶、、双和终。

In addition,the homeologous multivalent s have been observed in spreads of zygotene but these multivalents were ultimate ly resolved.

偶 还观察到由同祖配对形成的多价体，但随后阶段中这些多价体消失。
