Several neutrality tests use outgroups to infer the ancestral and derived states for polymorphism data. However, homoplasy can result in the incorrect inference of the derived variant. We show that empirically derived rates of misorientation strongly influence Fay and Wu's H-test, especially when the sample size is large.
几种中性检验使用外类群来推断多态性数据的祖先状态和衍生状态。然而，平行进化可能导致对衍生变异的错误推断。我们表明，根据经验得出的方向错误率会强烈影响费伊和吴的H检验，尤其是在样本量较大时。
