*The optimal number of PLS components, as determined by 10-fold cross-validation.
†R2 values for a PLS model with 1 component.
‡The 1-component R2 divided by the number of SNPs in the PLS component with nonzero regression coefficient, which are 5920, 6835, 759, 580, 143, and 150 SNPs, respectively.
