Question

multiple choice question
which method of phylogenetic tree construction is based on the percent difference between pairwise sequence alignments?

○ maximum parsimony
○ maximum likelihood
○ evolutionary distance

Explanation:

Maximum parsimony builds trees by minimizing evolutionary changes, not percent sequence differences. Maximum likelihood uses statistical models of sequence evolution. Evolutionary distance methods calculate pairwise sequence percent differences to construct phylogenetic trees.

Answer:

Evolutionary distance
