Additional file 7: Figure S3. of Genetic signatures of adaptation revealed from transcriptome sequencing of Arctic and red foxes

Statistical parsimony networks for five genes in Arctic and red foxes, including exon and intron sequence. Circle areas are proportional to haplotype frequencies and inferred intermediate states are shown as black dots. N = Non-synonymous substitutions; S = synonymous substitutions. Allele color codes: blue = Arctic foxes; orange = red foxes; black = dog. Note that for some loci, dog and fox haplotypes were too divergent to be connected at the 95 % credibility limit
