QQ plot and Manhattan of the egg number traits. a The QQ plot shows the expected -log10 P-value (the x-axis) plotted against the observed -log10 P-value (y-axis). In the top left of the QQ plot, λ is shown as 1.004. b In Manhattan plot, the x-axis is the position of each SNP on the chicken chromosomes (34, 40, 63 indicate LEG64, W, and Z respectively), and the y-axis is the -log10 P-value. The horizontal red dotted line at the top indicates the genome-wide significant thresholds is 3.91 × 10− 7, line at the bottom represents the genome-wide suggestively thresholds is 7.82 × 10−6
