The number of clades in the given figure.

Introduction:

A clade is the basic unit of a cladogram. A clade is defined as a group of species with a common ancestor. The species are united by a single evolutionary pathway in a clade. The tips of the branches in the cladogram represent taxa. A node in a cladogram indicates that the two groups arose from a common ancestor.
