The other 35.3 per cent QTLs did not have any significant additive effects of their own but were also involved in epistatic interactions.
其它35.3%的QTL没有本身的加性效应，却参与了上位性互作，这些位点可能通过诱发和修饰其它位点而起作用。
This might mean that the usual estimates of the QTL additive effects could be confounded by epistatic interactions and result in biased estimation.
因此传统方法对QTL加性效应的估算会由于上位性的影响而有偏。
