^aSim 5 = simulated data with a 5% missing rate for all SNPs; Sim 50 = simulated data with a 50% missing rate for all SNPs; Sim rand = simulated data with a random error rate in the range of 5 to 50%; Sim real = simulated data with a random error rate in the range of 5 to 10% for 5 SNPs and 10 to 50% for 10 SNPs; Real data = data from the Finnish Rainbow Trout Breeding Program

^bAccuracy calculated as N_Correct/N_Total, where N_Correct is the number of correct predictions and N_Total is the total number of predicted samples
