Fig 6. Haplotype clustering network around Ace1.

A) Minimum spanning tree of haplotypes around the 280S-linked variant 2R:3481632 (± 300 bp, n = 104 phased variants). Node size reflects number of haplotypes belonging to each cluster, which are color-coded according to species and geographical origin. Edges link haplotype clusters separated by one substitution. Singleton clusters have been removed from this view (see S10 Data). A cluster of identical haplotypes linked to the 280S-tagging variant is highlighted in green. B) Venn diagram representing the overlap of samples belonging to the 280S-linked haplotype clusters identified around each of the three tagging variants (S10 Data).
