Phylogenetic Network - Rooted Vs Unrooted

Rooted Vs Unrooted

Unrooted phylogenetic network

Let X be a set of taxa. An unrooted phylogenetic network N on X is any undirected graph whose leaves are bijectively labeled by the taxa in X. A number of different types of unrooted phylogenetic networks are in use like split networks and quasi-median networks.

Rooted phylogenetic network

Let X be a set of taxa. A rooted phylogenetic network N on X is a rooted DAG where the set of leaves is bijectively labeled by the taxa in X.
