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

染色易位有的来源于同祖换，有的来源于单价错分裂或断裂的重。

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

线期还观察到由同祖形成的多价，但随后阶段中这些多价消失。
