Table 1 Prediction accuracy for milk, fat and protein yields of sires with phenotyped daughters, using single trait analysis (ST), multi-trait analysis (mBLUP) and meta-analysis (MetaGS)

From: MetaGS: an accurate method to impute and combine SNP effects across populations using summary statistics

Trait	Val\Ref	ST		mBLUP		MetaGS
Trait	Val\Ref	JER	HOL	JER	HOL	JER	HOL
Milk	JER	0.52	0.32	0.50	0.49	0.53	0.50
Milk	HOL	0.05	0.51	0.46	0.52	0.46	0.52
Fat	JER	0.34	0.18	0.37	0.36	0.37	0.36
Fat	HOL	0.00	0.52	0.31	0.53	0.30	0.53
Protein	JER	0.55	0.15	0.54	0.39	0.54	0.40
Protein	HOL	0.08	0.48	0.39	0.53	0.40	0.53

The values represent the prediction accuracy (as the correlation coefficient between DGV and the phenotypes of the validation population) for the validation population (rows) using SNP effects calculated on the reference population (columns)
