Fig. 1From: Genome-wide association study of 17 serum biochemical indicators in a chicken F2 resource populationPearson correlations between phenotypes. The Pearson correlation coefficients of pairs of traits were calculated, and the traits were clustered based on the correlation coefficients. The colors (numbers) represent the pairwise correlation coefficients of the serum biochemical indicators. Red indicates a positive correlation, and blue indicates a negative correlationBack to article page
