Distribution of p values from GLM Model. A fixed effect linear model was constructed to test for association between segregating sites (variants) and disease severity scores. A main effect only model was built using all variables in the input data (ocular disease severity score, respiratory disease severity score, general signs disease severity score and total disease severity score). A separate model was built and solved for each trait and variant. Significant associations shown to the left of the dashed line (n = 4)
