Abstract	The objective of this paper was to study the genetic correlations of the visual scores traits with the growth continuous traits, by applying bayesian statistic methodology, using two-trait analyses under linear-threshold animal models. The morphological categorical traits of musculature, physical structure, conformation and sacrum were studied in animals of the Nelore breed at the age of 8, 15 and 22 months, and also in adult cows; and the growth continuous traits, weights at the age of 210, 365 and 450 days old, as well as the adult weight of the cow. Estimates of genetic correlations between these visual scores (musculature, physical structure and conformation) with the growth traits were favorably positive, indicating that the selection of one of them will bring genetic progress to another. The results achieved in this study also indicated that the physical structure and the conformation are determined, to a large extent, by the same sets of genes as the weight. In the same way, the evaluated visual scores in adult cows presented high genetic correlations with the adult weight of the cow. As concerning the sacrum, the estimates of genetic correlations were low and negative. KEY WORDS: Gibbs sampler, morphological traits, weights, zebu cattle.
