Robustness of tree topology to recombination. a Phylogenetic tree built on the clonal simulation of the core genome of A. pittii. The tree was evolved in silico without recombination. b Phylogenetic tree obtained from the simulated core genome of A. pittii recombined in silico. Each site of the clonal core genome with phylogenetic signal was exposed to exactly one recombination event. As a result, nearly all informative sites (96.4%) are incongruent with the true topology of the tree
