Intercept (\({b}_{0}\)) of the regression of \({\text{ACC}}_{\text{GEBV}}\) on \({\text{ACC}}_{\text{IP}}\). direct: all genotyped animals (N = 54,533) and phenotypes with direct \({\textbf{G}}^{-{\bf{1}}}\); apy: all genotyped animals (N = 54,533) and phenotypes with APY \({\textbf{G}}^{-{\bf{1}}}\); 50K-2K: all phenotypes and decreasing the number of genotyped animals from 50K to 2K; core: genotypes for core animals only (N = 15K) and all phenotypes; hacc: genotypes for high accuracy animals only (N = 15K) and all phenotypes; core_prog: genotypes and phenotypes for core animals plus their progeny phenotypes; hacc_prog: genotypes and phenotypes for high accuracy animals plus their progeny phenotypes
