Fig. 3: The Manhattan and Q-Q plots for nine traits.
The nine traits shown in Fig. 3 were the main focus of our study and were strongly correlated with both growth traits and carcass traits. In addition, the pairwise correlation coefficients for six growth traits (BW8, BW10, BW12, BBL12, SL12, and BSL12) were >0.77, located in the central red block in Fig. 1a. Similarly, strong correlation events were also observed for three carcass traits (CWe, SEW, and EW), of which pairwise correlation coefficients were >0.99, located within the red block at the left top (Fig. 1b). Each dot in this figure corresponds to an SNP within the data set. In each Manhattan plot, the dot color indicates the chromosome on which the SNP is located, the dot position indicates the −log10-transformed P value of the SNP, the number below represents the chromosome number, the length of the figure above the number represents the length of the chromosome, and the color represents the number of SNPs on the chromosome. The horizontal red dashed line denotes genome-wide significance (−log10(P) > 5.72). For each Q-Q plot, the x axis represents the expected −log10-transformed P value, the y axis shows the observed −log10-transformed P value, and the red line is the diagonal line.
