NMDS analysis of the gene expression differences between two populations. Normalized gene expression data for 120 European (CEU) and African (YRI) samples was obtained from the Genevar site and analyzed with Chipster's NMDS tool as described in the second case study of this article. The samples segregate to different parts of the plot, indicating that there are differences in gene expression between the populations.
