Researchers neglected the influence of sampling error, and small samples from F2 populations further reduced the variation. These deficiencies may result in wrong conclusions.
研究者对抽样误差的影响估计不足，所谓F2株系的小样本抽样，又进一步缩小了株系内变异程度，这就有可能出现假阳性的结果。
Frequency tracking means that sampling intervals of following sampling is updated according to new frequency estimation, so synchronous sampling error will be reduce step by step.
