Minimum spanning network of 4881 bps of phased sequence. See Figure 5 for specific breed and grey wolf haplotype labels. Node size correlates to the frequency of the haplotype across all samples. Hashes indicate the number of pairwise differences between haplotypes. Yellow nodes indicate the small dog IGF1 haplotypes and the blue nodes indicate the large dog IGF1 haplotypes. Dashed lines display alternative connections between haplotypes.
