Contour map of y ∕ Max(x 1, x 2) for a nucleotide character which assumes the JC model over the branch length space of A) the Huelsenbeck and Hillis [22] model tree and B) the Siddall [26] model tree, with contour lines of y ∕ Max(x 1, x 2) = 1/10, 1/6, 1/4, 1/2, 1 (thick dashed), 2, 4, 6, and 10 shown if present within the respective branch length space. Contour map of Πy for a nucleotide character under the JC model over the branch length space of C) the Huelsenbeck and Hillis [22] model tree and D) the Siddall [26] model tree, with contour lines of Πy = 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, and 1.0 (thick dashed) shown if present. Contour map of Π ∕ Max(x 1, x 2) for a nucleotide character under the JC model over the branch length space of E) the Huelsenbeck and Hillis [22] model tree and F) the Siddall [26] model tree, with contour lines of Π ∕ Max(x 1, x 2) = 1/10, 1/6, 1/4, 1/2, 1 (thick dashed), 2, 4, 6, and 10 shown if present.
