The chiasmata can slip off the ends of the bivalents, and thus chiasma frequency may be reduced by terminalization.
有时交叉以从二处滑开,因此移过程以降低交叉频率。
Terminalization The movement of chiasmata to the end of the bivalent arms, a process that may occur during late prophase I of meiosis.
交叉)移:在第一次减数分裂后期,染色交叉向二染色臂的移动的过程。

At the sites where exchange happens, chiasmata formed.
在发生换的地方,形成了。
The chiasmata remain on the chromosomes until they are at the transition to anaphase 1.
留在染色体上,直到它到后期 1。
At this stage, non-sister chromatids may cross-over at points called chiasmata (plural) , (singular: chiasma) .
在这个阶段,非姐妹染色单体可能会。
However, the homologous chromosomes of each bivalent remain tightly bound at chiasmata, the regions where crossing-over occurred.
然而,每个二价体的同源染色体仍然紧密结合在部位,也就是发生的区域。
