Figure 2From: Maximum likelihood models and algorithms for gene tree evolution with duplications and lossesReconciliations. Reconciliations for the gene tree G and the species tree S. Only two mappings from G to S exist: the lca-mapping m*, and the mapping m f . There are 4 possible reconciliations: R*, R1, R2 and R f . The diagram presents the embeddings of G, S, in which T*, T1, T2 and T f corresponds to R*, R1, R2 and R f , respectively. Only node x is the lca-speciation.Back to article page
