Accuracy of DGV for a random subset of 500 Australian Holstein (HOL-AUS) bulls with prior Information from Nordic Holstein (HOL-NOR). Priors were tested for a segment sizes of 100 (red), 250 (orange), 500 (green), 1000 (blue), 2000 (purple) or 3000 (cyan) SNPs. X axis shows different weights on the prior information relative to the information from the data. Horizontal black lines are accuracies obtained using BayesR. BayesRS accuracies showing significant difference from the accuracy obtained using BayesR at a 5% significance level are marked with *. The test was only applied for single traits, and not for the mean.
