## Figure 4.
Residual plots. Residual plots of internodal distances of each of four nuclear loci obtained from
regression against RAG-1 internodal distances (independent variable) on MP tree reconstructed from combined
data sets of 5 nuclear loci. (a, b), FGB7; (c, d), ADH5; (e, f), GPD3-5; and (g, h), myo-2. Note the higher variance of residuals in non-Charadriiformes (left panel) than Charadriiformes
(right panel), indicating better correlation of estimates of internode lengths in
the latter across all loci.
