Genome-wide association study for polyneuropathy in Leonberger dogs. a Note the association signal on chromosome 15. b The quantile–quantile (QQ) plot shows the observed vs. expected log P-values. The straight line in the QQ plot indicates the distribution of SNP markers under the null hypothesis, and the skew at the right edge indicates those markers that are more strongly associated with the trait than would be expected by chance. Markers from chromosome 15 are shown in red
