Q-Q Plots comparing p-values for the association between SNPs and height to the uniform distribution for different ancestry estimates. Figures depict the Q-Q plots comparing (A) the -log(unadjusted p-values); (B)-log(local adjusted /p/-values) (C) -log(global adjusted /p/-values) and (D) -log(both local and global adjusted p-values) to the theoretical uniform distribution.
