A-AM animal model with pedigree-based relationship matrix using VC estimated from A-AM, H-AM animal model with combined pedigree-based and genomic relationship matrix using VC estimated from H-AM, H-AM(VC-A) animal model with combined pedigree-based and genomic relationship matrix using VC estimated from A-AM

aPredictive ability is correlation between predicted breeding value and corrected phenotype

bBias of predicted breeding value is measured by the regression coefficients of predicted breeding values on corrected phenotypes, deviation from unity indicates a bias (inflation or deflation) in breeding values

cRegression coefficients of predicted breeding values on corrected phenotypes
