Manhattan and Q-Q plots of single-Locus GWAS based on imputation using SWIM reference panel for four growth traits. (A, C, E, G) Manhattan plots for 2-BW, 2-BL, 2-BH, 4-BH. (B, D, F, H) Quantitative-Quantitative (Q-Q) plots for 2-BW, 2-BL, 2-BH, 4-BH. The solid line represents the genome-wide significance level (9.25 × 10^− 8); The dashed line represents the suggestive significance. Abbreviations: 2-BW = body weight at 2 months, 2-BL = body length at 2 months, 2-BH = body height at 2 months, and 4-BH = body height at 4 months
