The out group in this cladogram is protozoa that is distantly related to the other organism s in the given cladogram.
The out group is a creature that is only distantly connected to the other creatures on the cladogram. The out group, which is commonly assumed to represent the ancestral situation from which the organisms in the cladogram later evolved, contributes to the tree's roots.
The organisms in the in-group are connected to one another. The cladogram is founded on the introduction of a distantly related creature known as the out group. The out group is frequently represented by a single branch on the cladogram.
Out group is an evolutionary phrase that refers to a taxon or lineage that is not part of the taxon group being examined.
Thus, the out group in this cladogram is protozoa.
