Cluster = genetic clusters inferred using STRUCTURE. Estimates were obtained using three different approaches (see Materials and Methods): resampling of alleles (analysis 1), allele freq. (analysis 2), equal freq. (analysis 3). The analyses were performed using (a) the complete set of genotypes assigned to a cluster, (b) excluding genotypes containing low-frequency alleles (<0.02), (c) excluding genotypes containing non-private low-frequency alleles.

¹no low-frequency alleles in population;

²no private alleles in population;

³all low-frequency alleles were private.
