Variation in 11 single-copy balancing selection candidates (BS11), TAP1, a target of BS tightly linked to MHC, and 154 control (CR) genes. (Means ± s.d. are given; L, re-sequenced length in bp; S, number of segregating sites per site in pooled sequences from all populations; π, nucleotide diversity per site, average of population means; μ, mutation rate per site per generation; Tajima's D, average of population means; Ss, number of shared polymorphisms per site in pairs of population groups; Sxf, fraction of sites with the derived variant fixed in one population group and polymorphic in another, summed for pairs of population groups.)
