Figure 2From: Haplotype structure and linkage disequilibrium in chemokine and chemokine receptor genesReduced median (R-M) Network of haplotypes of 14 SNPs in 3p21. Haplotypes indicated comprise nearly 80 per cent of the variation in the total population sample (N = 690). The size of the circle for each haplotype indicates the frequency of the haplotype in the pooled sample.Back to article page
