From the research we've done, the main risk is that doing this produces chromosomal damage in at least half, if not 70 per cent, of eggs.

从我们的研究了解到，主要的风险来自对卵细胞染色体的破坏，就算没有70%至少也有一半多。

Several factors, such as defects in chromosome segregation and DNA damage response, failure of cell cycle checkpoint, telomere dysfunction, may cause chromosomal instability.

多种细胞机制功能障碍将导致染色体不稳定性，包括染色体分离、DNA损伤反应、细胞周期检查点、端粒功能等。

Finally, comet assay, micronucleus and chromosomal aberration test were used to study and estimate the genetic damage effect of lead on occupational exposure workers.

第三部分，采用彗星试验、微核试验和染色体畸变试验检测和评估职业接触铅人群的遗传损伤效应。
