1·The divergence of CP gene sequences and biological symptoms indicated that there was much molecular variability on KRL-1.
根据KRL-1与其他分离物CP基因序列和生物学症状上的差异，可推断KRL-1存在较大的分子变异。
2·CONCLUSIONS: the limit of detection for any given MD syndrome is constrained by 4 factors: fetal fraction, MD size, coverage, and biological and technical variability of the event region.
结论：4个因素制约给定的MD综合征的检测极限，包括事件区域的胎儿碎片，MD大小，覆盖范围和生物及技术的变化性。
