Genome-wide association study for atypically small vulvae in 1835 German Landrace sows. Manhattan plot (a) representing the association of 50,649 SNPs with atypically small vulvae in the German Landrace population. The dots above the dashed line represent SNPs with P values less than 9.87 × 10−7 (Bonferroni corrected significance threshold) and Quantile-quantile plot (b). The grey shaded area represents the 95% concentration band under the null hypothesis of no association. Triangles represent SNPs with P values less than 9.87 × 10− 7
