(A) The number of aligned sites (N_sites), the number of polymorphic sites (S), the number of divergent sites (K) and Watterson’s polymorphism estimator (θ_W). (B) Number of pairwise differences between the four individuals. Note that values are the average of the pairwise comparisons of the unphased haplotypes, thus explaining why in some case the number are not integers.
