Gain and loss of COGs in internal nodes of the genome-tree according to PARS-G algorithm: g = 0.9. The boxes contain the number of gains (numerator) and losses (denominator) associated with each internal node; the gains (top) and losses (bottom) for each extant species are shown under the letter designating the species.
