Tests for recombination applied to each gene family.

*These alignments returned significant results (p<0.05) for recombination in both tests and were analyzed as separate GARD-predicted fragments in quartet decomposition to avoid conflicting phylogenetic signals.
aPHI, Pairwise Homoplasy Index. P-values are for a null hypothesis of no recombination.
bGARD, Genetic Algorithm for Recombination Detection.
cKH, Kishino-Hasegawa test performed on phylogenies inferred from alignments between break points predicted by GARD. P-values are for a null hypothesis of congruent phylogenies i.e., no recombination. N/A – not applicable, where no recombination break points were detected.
