  1. The accuracy of estimated breeding values of successive selection stages as a function of the implementation of genomic selection and the used selection indices. 1: accuracy estimated genomic breeding value, 2: selection on performance and GEBV of ancestors and sibs, 3: selection on candidates own GEBV, 4: selection path "sire to dam", 5: selection path "dam to sire"
