Dendrograms of the uncorrected and corrected log2 ratios. (a) Clustering of the uncorrected log2 ratios of the unrelated samples for all 22 autosomal chromosomes (excluding chromosomes 15 and 19). The heatbar under the dendrogram indicates the ethnic origin of the sample (blue, YRI; yellow, CEU; purple, CHB + JPT). (b) Clustering of the wave corrected log2 ratios of the unrelated samples on the same autosomal chromosomes.
