Standard deviation of h, π and g estimates are shown in parentheses. n, the number of individuals; N, the number of haplotypes; h, haplotype diversity; π, nucleotide diversity; g, population growth parameter; SSD, sum of square deviation (goodness-of-fit to a simulated population expansion); Raggedness, raggedness index; NA, not applicable.
