Zygotene Chromosomes approximately line up with each other into homologous chromosome pairs through synaptonemal complex.

偶线期染色体通过联会复合体大致排列成同源染色体对。

Metaphase 1 Homologous pairs move together along the metaphase plate: the paired homologous chromosomes align along an equatorial plane that bisects the spindle.

中期 1同源染色体对沿着中期板一起移动：成对的同源染色体沿着将纺锤体一分为二的赤道平面排列。
