Three rooted phylogenetic trees shown in (a), (b), and (c) supported by 76%, 11%, and 11%, respectively, of all genes studied in Ebersberger et al. (2007). In (d), we show the cluster network and in (e) a (multicombining) galled tree, both representing all clusters contained in the three rooted phylogenetic trees. The line width of each edge is proportional to the number of trees that contain it. Adapted from Huson and Rupp (2008).
