ni, number of individuals and ns, number of DNA sequences of the samples (see Methods for further details); S number of polymorphic sites; π, average number of pair-wise differences; θ, neutral parameter, based on the number of segregating sites. Variances of π and θ values are shown in brackets. DT, Tajima's D [54]; FS, Fu's FS [55] and R2, Ramos-Onsins and Rozas' R2 [56]. *The Mesquita sequences were derived from the F1 of a single female and therefore no tests were carried out with this sample.
