Fig. 4From: Locus-aware decomposition of gene trees with respect to polytomous species treesAn example of a DTL scenario E for a gene tree G and a species tree S. E has two HGTs, one duplication, and three speciation events. The scenario is shown with the mapping M depicted for the internal nodes only. While the gene loss events are not formally modeled here, they are required when embedding a gene tree into a species tree according to a given DTL scenario. Therefore, our visualizations of DTL scenarios are extended by the required loss events (see also the scenario \(E_3\) in Fig. 5)Back to article page
