FIG. 6. A majority-rule consensus gene tree reconstructed from mtDNA cytochrome oxidase 1 in Redescription and Recognition of Etheostoma cyanorum from Blue River, Oklahoma

FIG. 6. A majority-rule consensus gene tree reconstructed from mtDNA cytochrome oxidase 1 (CO1) sequence data obtained from the Barcode of Life Database (BOLD). Maximum-likelihood (ML) and Bayesian trees had identical topologies. Branch lengths are proportional to inferred mutations. Shading of lineages represents samples from E. whipplei (outgroup) in black, E. cyanorum in gray, and E. radiosum in white. ML bootstrap proportions/ Bayesian posterior probabilities are reported.
