These translocation lines were generated from homeologous chromosome pairing, or mis-division and reconstruction of univalent chromosomes.

染色易位有于同祖配对交换，有于单价错分裂或断裂重建。

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

在偶 线期还由同祖配对形成多价，但在随后阶段中这些多价消失。
