in a cladogram, what occurs at a node?\na derived trait appears.\nevolution is stopped.\nan ancestor dies.\nthe cladogram ends.
Answer
Answer:
A. A derived trait appears.
Brief Explanations:
In a cladogram, a node represents a common ancestor. At a node, a derived trait (a new characteristic that has evolved) appears. Evolution does not stop at a node. A node does not signify an ancestor's death. Also, a cladogram does not end at a node; it continues to show further evolutionary relationships. So, the correct option is that a derived trait appears at a node.
