Summary statistics for samples from a local farm the group of escapees, and a local wild population.

N = number of samples analysed, Ho and He = observed and expected heterozygosity, Fis = inbreeding coefficient, HWE = number of deviations from Hardy Weinberg equilibrium at two significance levels, LD = observed linkage disequilibrium at two significance levels, At = total number of alleles observed over 17 polymorphic loci, Ar = allelic richness based upon a re-sample size of 36–37 per locus/population combination and then totaled over all loci, Ne = effective population size as estimated by the LDNA method [47], with 95% confidence intervals in brackets and based upon including alleles down to and including those with frequencies of 0.005 in each population.
