Relationship between the number of unresolved genotypes ( x -axis) and reduction in the total number of gene lineages ( y -axis). Top: simulated datasets (solid circles) and empirical datasets (open circles) examined under a PHASE confidence probability threshold of 0.90. Bottom: simulated and empirical datasets examined under the 0.60 threshold. Except for the empirical data under the 0.90 threshold, all regressions were significantly positive (P < 0.0001).
