From: A phylogenomic study of Steganinae fruit flies (Diptera: Drosophilidae): strong gene tree heterogeneity and evidence for monophyly

Fig. 2

The frequency of gene tree topologies for a four-species problem. Pie chart colors relate to the color of the gene tree topologies. The most frequent gene tree (in blue) matched the species tree inferred based on the full dataset (10 species) and recovered the Steganinae subfamily as monophyletic. Mismatch topologies are shown in orange and green. a The species tree and the mismatch topologies; b frequency of the gene tree topologies estimated from the phylogenomic dataset. c Distribution of the gene trees by Muller element (correspondence to D. melanogaster chromosomes: A-X, B-2L, C-2R, D-3L, D-3R, E-4)
