Variation of hemoglobin genes. a The sum of 3 hemoglobin genes (HBA1, HBA2, HBB) is correlated with PC1. PCC: Pearson Correlation Coefficient. Blood: manually curated blood samples; GTEx: GTEx blood samples; LCL: lymphoblastoid cell lines; WB: manually curated whole blood samples; Other: all other samples, which are colored as gray. b Similar to (a), but now we cut the log2(CPM sum) into four groups. The box shows the median, upper quartile and lower quartile of PC1 values for each group
