Population-specific values at HighD sites. (a) iHS values; (b) XP-EHH values. In both cases values of the two statistics relative to randomly selected genomic variable sites matched for allele frequency and distance from gene are also shown (indicated as ‘matched’ or ‘m_ ’, gray lines). P-values refer to two-sample Kolmogorov-Smirnov tests between iHS or XP-EHH distributions in HighD and matched sites. In (b), for every population XP-EHH was calculated using as reference the two others (two shades of pink or two line types).
