The importance of information on relatives for the prediction of genomic breeding values and the implications for the makeup of reference data sets in livestock breeding schemes

Table 1 Empirical accuracy¹ (± S.E.)² using genomic and pedigree based methods in simulated data.

¹ Calculated as the correlation between estimated and true breeding values for 250 animals with no phenotype. Breeding values estimated using genomic (gBLUP) and pedigree (BLUP-S and BLUP-D) based methods in simulated data for groups of animals with different relationships to the reference data set.
² Standard error of means of 10 replicates
