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.
