Figure 13 in Comparative osteology of the Danio (Cyprinidae: Ostariophysi) axial skeleton with comments on Danio relationships based on molecules and morphology

Figure 13. Comparison of phylogenies derived from morphological and combined data sets. A, Strict consensus for molecular data (581 steps; CI = 0.801); B, Strict consensus tree for combined morphological and molecular data sets (611 steps, CI = 0.861). Bootstrap values are given above each internode. Note that the relationships within the slender-bodied clade are identical in the two trees, but relationships within the deep-bodied clade differ in the two trees.
