Xta chiasmata

英 美
  • 交叉
  • chiasmata n.视神经交叉;染色体交叉
    1. Genetic recombination can occur without the formation of a chiasmata.
      遗传重组在没有形成交叉的情况下,也可以发生。
    2. The chiasmata can slip off the ends of the bivalents, and thus chiasma frequency may be reduced by terminalization.
      有时交叉可以从二价体末端处滑开,因此移端过程可以降低交叉频率。
