Prediction of genomic breeding values for growth, carcass and meat quality traits in a multi-breed sheep population using a HD SNP chip

Table 6 Average observed accuracies of molecular breeding values group of animals clustered based on Euclidean Distance Matrix (EDM) or distance matrix built from G matrix and average ratio, K, of expected (assuming accuracies of molecular breeding values for each scenario) spread to observed spread of molecular breeding values
