Phenotypic and genetic correlations between growth traits in Qinchuan black (QCB) pigs. (A) Phenotypic and genetic correlations between growth traits in QCB pigs at two months. (B) Phenotypic and genetic correlations between growth traits in QCB pigs at four months. The upper triangle represents genetic correlation, the lower triangle represents phenotypic correlation, and the numbers in the ellipse represent specific correlation coefficients.
