Prediction accuracy for three different traits. Prediction accuracy for the barley inbreds for leaf angle, heading date, and plant height, for 66 cases which differ in their weights for the predictors sequence variants (SV), expression presence/absence variation (ePAV), and gene expression in seedlings (T _s). Their corresponding relationship matrices were joined with weights varying from 0 to 1 in increments of 0.1. Weights for SV and ePAV are shown at the respective scales; weights for gene expression are = 1 - weight of SV - weight of ePAV. Plotted values represent medians of prediction accuracy across 1,000 cross-validation runs. Heat color schemes differ for the three traits ranging from white, indicating the respective highest value, to red for the respective lowest value
