Summary statistics of HVS-I sequences in the North Iberian populations analyzed in the present article and other European populations.

N = sample size, k = number of different haplotypes (divided by N in brackets).S = Number of polymorphic (segregating) sites.Nmut = total number of mutations.H = haplotype diversity and standard error.�� = nucleotide diversity and standard error.M = average number of nucleotide differences.VO(M) = observed variance of M.r = Harpending's (raggedness) index.D = Tajima's test of selective neutrality.FL = Fu and Li's D* statistics.Statistical significance: *, P-value**P-value*1Present study.*2Loogv?li et al.
