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

Table 4 Approximate change of genetic trend in all considered trait complexes when the relative economic weight of a single trait complex is marginally increased, as obtained by the approach described in the methods section with \({\varvec{\theta}}=0.001\) for the new index

Results are scaled such that all absolute values in each line sum up to one. Diagonal values in italics represent the direct change in the modified trait complex, all other values are indirect changes in other trait complexes. Note that residual correlations for the new index were assumed to be zero, as they could not be estimated from the data. For trait complex abbreviations see Table 1
