Draw a phylogenetic network!


Welcome to ISIPhyNC, the Information System on Inclusions of Phylogenetic Network Classes, which provides information about subclasses of phylogenetic networks.

This website focuses only on rooted explicit phylogenetic networks, that is directed acyclic graphs with a root (a vertex of indegree 0) and leaves (vertices with outdegree 0) which are usually labeled by distinct labels corresponding to biological taxa.

Classes of explicit phylogenetic networks

Classes of binary networks

An arrow from class A to class B means that A contains B (another version of this graph, drawn with GraphViz, is available here).
To have more information about the subclasses and the proofs of inclusion, please follow the links in the list of subclasses below.
