A branching diagram that links entities by estimates of overall similarity.

A branching diagram (tree) showing the phenetic similarity among the terminal taxa (cf. cladogram, phylogram, dendrogram).

One of two major types of dendrograms, a tree-like diagram used to show similarity (or otherwise) among specimens or groups of specimens. It is based only on similarities in phenotypes.

A graphic representation that portrays or attempts to portray the taxonomic relationships among a number of findividuals, species, or higher taxa on the basis of overall similarities between them.
