^aRecombination events between ancestors of sequences in alignment.

^bRecombination events involving ancestor outside alignment or obscured by subsequent mutations.

^cSim. P value, similar P value. P values indicating statistically significant (P < 0.05) evidence for recombination events are marked with asterisks.

^dNumber of segments of alignment sufficiently similar to imply recombination.

^eGroup of fragments linked to the same 5′ and/or 3′ breakpoints were classified as a single recombination event.

^f“Multiple” refers to global inner recombination events that involved significant fragments between and within lineages.
