- Method one-step is the method advocated in this paper, method ped uses the pedigree based relationship matrix, and method two-step is the genomic prediction method using only genotyped animals (note that parameter estimates for this method cannot be compared to parameter estimates from the other two methods). Finally, one-step-2 differs from one-step in that it ignores the markers of selection candidates in the parameter estimation. The right-most column shows the correlation between the estimated and the true breeding value (BV).
