^aModels fitting a single SNP alone or with a polygenic effect based on pedigree relationships (\({\mathbf{A}}\)), or genomic relationships (GRM). Models using three, five, or ten SNP haplotypes are abbreviated with ‘Hap’ followed by the number of SNPs used to form the haplotype. Models using GRM for prediction are abbreviated with ‘GRM’
