<p>Graphs displaying genetic diversity (nucleotide diversity and haplotype diversity) of samples from the two major phylogeographic groups described in Liu et al <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0051122#pone.0051122-Liu1" target="_blank">[19]</a>, and the ancient DNA samples from British Columbia and Alaska, for A) D-loop (above) and B) cytb (below). Note the lower diversity of the northwest Pacific group and the close clustering of ancient samples with the modern samples from the northeast Pacific. The one outlying sample with low D-loop haplotype diversity is from Portage Inlet (southern Georgia Strait), which shows similar cytb diversity to the other samples.</p
