Minimum ancestral recombination graphs (ARGs) inferred from the FFSC datasets for the atp6, nad5 and nad6 using the BEAGLE branch and bound algorithm in SNAP Workbench 2.0 (Price & Carbone 2005). Haplotypes are colour coded according to the clade within the FFSC complex to which the species belong (“African” = red, “American” = blue, “Asian” = green). Circles with numbers represent recombination events and the number within a circle represents the nucleotide position of the recombination event for each dataset. After a recombination event, the two sequences are replaced with a recombinant consisting of a prefix (P) from one sequence and a suffix (S) of the other sequence. The numbers on the branches suggest the number of mutation events before the coalescence of the specific haplotypes.
