Question

Amar is making a cladogram. Out of all the species he is using, he knows that species X and Y are the least primitive and are the most closely related.

Where will these organisms most likely be placed on the diagram?

at two points close together toward the upper right of the diagram
at two points close together toward the lower left of the diagram
at two points far apart toward the middle of the diagram
at two points far apart toward the upper right of the diagram

Answer 1

at two points close together toward the upper right of the diagram

Explanation: on a cladogram the most derived (least primitive) taxa appear at the tips, and the most closely related species are adjacent tips on the same recent branch.
