Figure 2From: Distinguishing between hot-spots and melting-pots of genetic diversity using haplotype connectivityThreshold graphs. The graphs (a) G2(X) and (b) G5(X) induced by the haplotype phylogeny in Figure 1(b) on the subset Y = {b2, b4, ..., b12}. For example, there is no edge joining the haplotypes b2 and b10 in G2(X) because the number of edges on the path from b2 to b10 in the phylogeny is greater than 2.Back to article page
