Which is a feature of a cladogram?

the characteristics must be shared among the organisms.

the characteristics must be different among the organisms.

it must contain at least three different shared characteristics.

it must contain at least three different groups of organisms.

answer !

The characteristics must be shared among the organisms

Explanation:  

Cladogram is a diagram that shows us a relationship between different organisms.

At the top of the cladogram, you will have different organisms that you are looking at and you will have name of those organism. Along the side of the cladogram, you will have different characteristics and these characteristics are what separates the various organisms from one another. Cladogram are used to use to establish relationships between shared derived characteristics.

The characteristics must be shared among the organisms.

Explanation:

The cladogram is a diagram in which the evolutionary relationships between living beings are represented, for this the organisms must show characteristics shared among themselves. A cladogram is composed of the root, branches, nodes and terminals.

The root represents a probable ancestral group or species.

The knot is the point from which the branches, the branches, start. Each node indicates a cladogenetic event.

The branches are the lines of the cladogram and lead to one or more terminal groups. The groups of living beings make up the terminals in the cladograms.

the organisms are not adapted to live in some communities or habitats.
