  1. The observed proportion of SNPs significant was compared to the mean (μ) of the simulated null distribution (μ(PropSig)), created by permutation testing, to determine if the observed proportion was significant at an experiment-wise level (* denotes significant at P < 0.05 experiment-wise, ** denotes significant at P < 0.01 experiment-wise) (see Methods). The total number of SNPs is presented in bold.
