¹for trait abbreviations see Table 1, ²number of phenotypic observations, ³number of Angus individuals with a phenotypic record in this data set which have been used for deriving ANGUS, BOSTAURUS and ALL prediction equation, ⁴mean, ⁵standard deviation. Note that no Limousin individuals were used in the training set and all phenotyped Brahman individuals which where part of the training set were excluded from the analysis.
