  1. 1Genotypes of sires and maternal grandsires of phenotyped individuals not already included in the real scenario were added; 2within the testing set of 1344 cows, 539 had at least one offspring genotyped and were removed from the testing set for the offspring scenarios, hence there were only 805 cows in the testing set in Off0 to Off4.
