Supplementary Figure S6

Supplementary Figure S6 Pairs of short successive internal branches are consistent with expectations for the anomaly zone. Species tree topologies for CNEEs (a), introns (b), and UCEs (c) are shown with internal branch lengths in coalescent units estimated from best maximum likelihood gene trees with ASTRAL. Terminal branch lengths are uninformative and are drawn as a constant value across taxa. Coalescent branch lengths for all pairs of branches (x and y) are given in (d), with a(x) calculated following Equation 4 from Degnan and Rosenberg (2006). Anomalous gene trees are expected when y < a(x). Clades fulfilling this anomaly zone criterion are shaded in (d), with the corresponding branches indicated in a-c.
