Population genetic parameters for seven TcI populations.

*Two samples included in Figure 1 were excluded from population analysis due to DNA availability issues and consequential high levels of missing data.aAllelic richness (sample size corrected).bMean observed and expected heterozygosity across all loci.cProportion of loci showing a significant deficit in heterozygosity after a sequential Bonferroni correction.dProportion of loci showing significant excess heterozygosity after a sequential Bonferroni correction.eThe Index of Association.fP-value for index of association, calculated by comparison to a null distribution of 1,000 randomised datasets.N, number of isolates in population; G, number of multilocus genotypes per population; MNA, mean number of alleles per locus.
