Figure 4. I. scapularis 16S Bayesian phylogeny compared to other I. scapularis sequences from Genbank.
Tree is rooted to I. pacificus ( = brown) and included only sequences confirmed by blastn to be Ixodes scapularis. Pink = Mississippi samples; purple = Pennsylvania; red = specimens were blinded until after sequence confirmation. Numbers at nodes represent posterior probability values and branch length corresponds to number of substitutions.
