The observed and expected numbers of individuals with 0–5 introgressed alleles. The *G*-statistic tests against the null hypothesis that introgressed alleles are in linkage equilibrium (approximated by a Poisson distribution). The associated *p* value is calculated using the asymptotic χ^{2}-distribution. The last column gives the number of times the observed *G* value was exceeded in 1000 random permutations of the dataset. Significant deviations indicate introgressing alleles are in linkage disequilibrium, suggesting recent hybridization in that site.
