The top dendrogram (a) shows the clustering of the uncorrected log2 ratios for the unrelated HapMap samples for all 22 autosomal chromosomes. The heatbar under the dendrogram indicates the ethnic origin of the sample (blue, YRI; yellow, CEU; purple, CHB + JPT). The second dendrogram/heatbar (b) shows the clustering of the corrected log2 ratios on the same chromosomes.
