Median-joining network displaying ancient and modern D-loop haplotypes.

<p>Median-joining network displaying the relationships between the ancient D-loop haplotypes and modern herring populations from different geographical regions (modern datasets are those listed in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0051122#pone.0051122.s005" target="_blank">Table S2</a> from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0051122#pone.0051122-Liu1" target="_blank">[19]</a>). The majority of the ancient samples cluster with modern herring in the two lineages from the northeast Pacific (lineages B and C). Lineage A is distinguished by 3 polymorphisms (15682C, 15841C, 15838G, coordinates based on Genbank accession NC009578); Lineages B and C are distinguished by three polymorphisms: lineage B resembles NC009578, while lineage C is defined by 15670C, 15823G, 15831T.
