[Polytomy losses labeled with the names of the species from which they are absent.] [Polytomy losses labeled with the number of species from which they are absent.]

Figure 5.2: A binary gene tree reconciled with the non-binary species tree in Figure 4.1. Conditional duplications are marked by pink cD’s, while required duplications are indicated with red D’s. Polytomy losses are labeled with the name of the associated polytomy, as well as the information about the species from which they are absent.
