In the Unweighted Pair Group Method (UPGMA)of Determining Evolutionary Relationships

Question

In the unweighted pair group method (UPGMA)of determining evolutionary relationships,
A)each set of taxa is connected by the shortest genetic distance.
B)a constant rate of evolution across all lineages is assumed.
C)a distance matrix is first constructed.
D)A and B only
E)A,B,and C

Accepted Answer

In UPGMA, each set of taxa is connected by the shortest genetic distance (A), and a distance matrix is first constructed (C). Additionally, a constant rate of evolution across all lineages is assumed (B). Therefore, the correct answer is E, as all three options are true.
