Prophase may be divided into successive stages termed leptotene, zygotene, pachytene, diplotene, and diakinesis. 前期可被分为连续的阶段：细线期、偶线期、粗线期、双线期和终变期。
In addition,the homeologous multivalent s have been observed in spreads of zygotene but these multivalents were ultimate ly resolved. 在偶 线期还观察到由同祖配对形成的多价体，但在随后阶段中这些多价体消失。
Further examinations revealed the gold particles representing actin in SCs of autosomes and sex chromosomes and also in SCs of zygotene and pachytene. 观察到，常染色体SC和性染色体SC以及偶线期和粗线期SC中都含有肌动蛋白，肌动蛋白分布于SC的端部和侧生组分上，代表肌动蛋白的胶体金颗粒在SC上往往成簇存在。
The karyotype of Nelumbo nucifera during meiosis zygotene was established in this study, which would help the studies of meiosis and molecular cytogenetics in lotus. 摘要本研究建立了中国莲偶线期染色体的核型，为研究莲的减数分裂过程及分子细胞遗传学研究提供基础。

Zygotene is characterized by the active and specific pairing(synapsis) of homologous chromosomes leading to the formation of a haploid number of bivalents. 偶线期时，以同源染色体活跃的、特定的配对（联会）为特征，形成了单倍数的二价染色体。
