Introgression was assessed via Patterson’s D between global populations of Aaa/Aaf and colonies within Rabai, illustrating bidirectional gene flow between the two forms. Local peaks of introgression were identified using Martin’s ƒD. Ancestry-informative markers were selected as those with Fst > 0.8 between all pure Aaa/Aaf colonies and illustrate the assymetric nature of introgression in this region, with a higher proportion of Aaf alleles found within the Aaa and hybrid colonies than vice versa
