The chiasmata can slip off the ends of the bivalents, and thus chiasma frequency may be reduced by terminalization.
有时交叉价体末端处滑开，因此移端过程降低交叉频率。
Terminalization The movement of chiasmata to the end of the bivalent arms, a process that may occur during late prophase I of meiosis.

The chiasmata remain on the chromosomes until they are at the transition to anaphase 1.
交叉保色体上，直到它们过渡到后期 1。
However, the homologous chromosomes of each bivalent remain tightly bound at chiasmata, the regions where crossing-over occurred.
然而，每个二价体的同源色体仍然合交叉部位，也就是发生交叉的区域。
At the sites where exchange happens, chiasmata formed.
发生交换的地方，形成了交叉。
At this stage, non-sister chromatids may cross-over at points called chiasmata (plural) , (singular: chiasma) .
这个阶段，非姐妹色单体可能会交叉。
