Figure 1From: The influence of genetic variation in 30 selected genes on the clinical characteristics of early onset breast cancerInference of ancestry by multidimensional scaling. POSH and HapMap samples plotted for the first two principal components obtained by multidimensional scaling of a matrix of pairwise identity by state values. Excluded POSH samples, filled black circles, occur near the YRI and CHB+JPT clusters. CHB, Chinese; CUE, Western European; JPT, Japanese; POSH, Prospective study of Outcomes in Sporadic versus Hereditary breast cancer; YRI, Nigerian.Back to article page
