Simulation results. a Simulations were carried out under neutrality, and tests for selection [−ln combined p values for Tajima’s D and Fay and Wu’s H (top) or Nielsen et al.’s CLR (bottom)] were calculated in non-overlapping 10 kb windows across 300 kb. Values of the test were averaged over 16 independent neutral simulations that passed the XP-EHH filter. No departures from neutrality were seen. b 1,752 simulations with selection (selection coefficient 0.001, 0.004, 0.007, 0.01) that passed the XP-EHH filter and neutrality tests were averaged as in a. Departures from neutrality are seen most strongly in the window containing the selected SNP. c. The distribution of the top signal (lowest combined p value) or highest CLR in each simulation is shown across the 300-kb region. d. Probability that the known selected variant is found at each distance from the peak test value
