[Identification of ancestral genes untroducing incongruence between gene and species tree].
The article introduces two novel approaches to detect potential incongruence between the protein family tree and the species tree. The first approach implements substitution of a known mapping of gene tree G into species tree S with somewhat analogous multivalued G-into-S "mapping". The second approach is based on elementary concepts from the fuzzy-set theory. Detailed description of the two corresponding algorithms is provided with demonstration of their performance on a model example and on three biological COGs.
