Fig. 2From: Partitioning of genomic variance reveals biological pathways associated with udder health and milk production traits in dairy cattleQQ-plot of the observed likelihood ratios (LR) of random gene groups vs. theoretical \({\chi ^{2}_{1}}\)-distribution showing that they are skewed towards higher values than \({\chi ^{2}_{1}}\). LR displayed for the traits Mastitis 1.1 (top) and Fat yield (bottom), conditional on whether the gene groups contain one of the DGAT1 genes (left/right) and group size (colour). Please note that the range of the y-axes differs between the top and bottomBack to article page
