chiasmata

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)移端：发生在第一次减数分裂后期，染色体交叉体染色体臂的末端移动的过。

The chiasmata can slip off the ends of the bivalents, and thus chiasma frequency may be reduced by terminalization.

有时交叉可以从体末端，因此移端过可以降低交叉频率。
