Figure 2From: Genomic diversity of the human intestinal parasite Entamoeba histolyticaEvidence of historical recombination among E. histolytica. The proportion of 100,000 randomly sampled pairs of polymorphic sites showing 4 haplotypes calculated for 100 distance intervals, plotted against the median distance for each interval. The positive correlation is highly significant, Spearman's rho = 0.83 (P < 2.2 × 10-16).Back to article page
