Fitness difference (WD) among HIV clones calculated as reported previously.20 (a) Results from all competitions involving the wild-type clade B isolate (B.wt). (b–h) Results from all competitions involving the isolate in the graph title of each panel. Bars reflect fitness differences calculated from pairwise competitions between each isolate. WD < 1 denotes competitions in which the isolate in the x-axis was fitter. WD > 1 denotes competitions where the isolate in the graph title was fitter.
