Observed fractions of disrupting recombination events that occur in lineages ancestral to members of the outgroup clade in yeast ARGs.

Each row reports the results of analysis of ARGs inferred from empirical yeast data. Each fractional value indicates the frequency with which, given a region whose inferred genealogy positioned the indicated clade as an outgroup, the recombination event at the region's boundary occurred in a lineage ancestral to the outgroup clade. Total tree size was in each case. , clade size.
