Analysis of overall recombination (PHI test) and individual recombination events (Sawyers’ runs test).

a Gene conversion test for recombination between ancestors of sequences in an alignment (global inner recombination) [94, 95]. Global outer recombination events were not detected.b Global p value obtained using 10,000 permutations.c Fragment shared by two sequences in the alignment via ancestral gene conversion [94]. Only fragments that significantly (p d Groups of fragments linked to the same 5' and/or 3' breakpoints were classified as a single recombination event as described by Nightingales et al. [95] and den Bakker et al. [96].e Recombination events both between and within lineages.f Not determined due to the lack of parsimonious sites.g Significant (p Analysis of overall recombination (PHI test) and individual recombination events (Sawyers’ runs test).
