Evaluation of the performance of first-generation SNP panels in capturing common variance among the Yoruban, Asian and Estonian population samples compared to the CEPH population sample. The relative ratio of markers covered (A,B) and the relative ratio of mean r2 between markers and their best tagSNPs (C,D) for the CEPH, Asian, Yoruban and Estonian population samples in two ENCODE regions (Chromosome 2: ENr112 on 2p16.3 and ENr131 on 2p37.1). Only markers present in the Estonian population sample were used to measure the percentage of markers covered and the mean r2 between markers and their best tagSNPs. The results are expressed relative to the CEPH population sample.
