Answer:
A derived trait or character
Step-by-step explanation:
A cladogram reveals the relationship between species of the same ancestors by showing the trait right from the ancestors and how they have modified such traits. The cladogram is usually a tree-like diagram that places the first parents as the root.
Character or trait is usually used to group the generations into a clade and subclades in a cladogram. At any point when there is a divergence of a trait from that of the parents, a new branch is created representing a new clade.
These traits that define the subclades are known as derived traits and they are the specific trait that is used to construct a cladogram
