Inparalogs and multiple species. (a) is a connected component of the similarity graph (see Section Experiments on real datasets for a description of the data) consistent with the gene history depicted in (c). With the complete information from all four species there are no inparalogs inferred, as the duplication d is above the speciation between mouse and rat. (b) is the subgraph of (a) with rat removed from consideration. One inparalog is inferred in the mouse with respect to human and chimp (as depicted in (d)).
