Phylogeny of the genomes examined showing numbers of contemporary pseudogenes that arose on each branch. In a few cases, the distribution of a pseudogene allowed inference of its loss by a particular lineage (negative numbers). Total numbers of pseudogenes (that can be mapped onto the tree) are shown after strain designations. Convergent pseudogenes correspond to those that occur in the same gene with the same mutations but that arose independently based on their phylogenetic distribution. The black circles represent the presence of the convergent pseudogenes in the given species, and the white circles correspond to their absence. The numbers over the box indicate the number of pseudogenes with the given pattern.
