Answer: Xiao can use these structures to create a similarity matrix that enables to differentiate between synapomorphies and homoplasies.

Explanation: A synapomorphy is a trait that has been inherited from the same ancestor, this trait enables to establish a relation of homology between two or more species; while a homoplasy is an analog structure that doesn't have homology.
