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

前期可被分为连续：细期、偶期、粗期、双期和终变期。

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

在偶 期还由同祖配对形成多价体，但在随后中这些多价体消失。
