^aAverage and standard error (as shown as subscripts)
^bEBV_P = estimates of breeding value based on pedigree information; EBV_P _&Y = estimates of breeding value based on pedigree and phenotype information; EBV_M = estimates of breeding value based on marker information (in generation 20 estimates of breeding value are based on marker and phenotype information, i.e., EBV_M _&Y)
^cin generation 20, the results are presented separately for females (f) and males (m), because males have own phenotype records, whereas females do not
