θ = effective mutation rate estimated from equilibrium heterozygosity [θ(Het)], number of alleles [θ(k)], number of polymorphic sites [θ(S)] and nucleotide diversity [θ(π)]. The last 3 rows correspond to different statistics of neutrality at the population level. S.D. = standard deviation; C.I. = confidence interval. NS: P>0.05; * = P<0.05.
