Table 4 Accuracy of GEBV, bias of prediction and coancestry coefficients of top ranking animals (mean over 100 replicates ± standard deviation) on GEBV estimated from individual records and from group records
Records | Model | Accuracy (SD) | Bias (SD) | Coancestry coefficients (SD) |
|---|---|---|---|---|
Individual records | GBLUPi | 0.825 (0.020) | 1.011 (0.041) | 0.036 (0.009) |
Group records from supervised clustering method based on genomic relationships | GBLUPgr | 0.762 (0.028) | 1.007 (0.054) | 0.041 (0.010) |
Group records from unsupervised clustering method based on genotypes | GBLUPgr | 0.758 (0.030) | 1.009 (0.054) | 0.041 (0.009) |
Group records from random grouping of full-sibs | GBLUPgr | 0.749 (0.032) | 1.015 (0.060) | 0.043 (0.010) |
Group records from random grouping of paternal half-sibs | GBLUPgr | 0.682 (0.040) | 1.017 (0.092) | 0.049 (0.010) |
