How economic weights translate into genetic and phenotypic progress, and vice versa

Table 1 Trait complex names and abbreviations, economic weights in the old and the new index, reliability of genomic breeding values (\({{\varvec{\rho}}}_{{\varvec{i}}}^{2}\)), heritabilities (\({{\varvec{h}}}_{{\varvec{i}}}^{2}\)) and genetic correlations among all traits
