Proportion of significant transcripts by overall heritability. (A) Unadjusted expression data and SNPs from the Illumina 300K panel in the MRCA subjects. (B) PC-adjusted expression data and the imputation of 1000G SNPs in the MRCA subjects. (C) Unadjusted expression data and SNPs from the Illumina 300K panel in the MRCE subjects. (D) PC-adjusted expression data and the imputation of 1000G SNPs in the MRCE subjects. The number of transcripts in each heritability category is given at the bottom of each bar.
