Cladograms and Taxonomy 2024y

What is the purpose of a cladogram?

• To visualize relationships between groups of organisms by looking at shared traits.

• To trace the inherited traits of a single species over time.

• To check the likelihood of an offspring having a particular trait.

• To monitor mutations that arise among different populations.
