(A) Manhattan plot for −log10 p-values of marker effects for residuals for fecal larvae counts of Dictyocaulus viviparus (RES-DV); markers above the genome-wide significance threshold pBonf (red dashed line) are highlighted in red and markers above the suggestive significance threshold pSug (blue dashed line) are highlighted in blue. Markers within a distance of 125 kb up- and downstream of the significantly or suggestively associated SVs are highlighted in red or blue, respectively. (B) Regional association plot for the docking protein 6 (DOK6) gene on BTA 24 with corresponding flanking regions (+/−100,000 bp). The SNP rs384171524 (blue square) was the highest associated SNP (p = 1.04 × 10−14) for RES-DV. Circles show GWAS p-values, with different colors indicating linkage disequilibrium (LD): red: LD 0.8 to 1.0, orange: LD 0.5 to 0.8. yellow: LD 0.2 to 0.5, gray: LD 0.0 to 0.2.
