4. Assuming that Moss is the outgroup (the species on bottom
outside the others), draw all three possible trees of evolutionary
relationships among these species. Label your trees A, B, and C.
Note – you may draw these by hand.

5. Calculate a genetic distance matrix for these sequences. Based
on these values, which tree (A, B, or C) do you think is best under
the Genetic Distance criterion?

6. Determine the minimum number of mutations required under the
parsimony criterion for each of the three trees. Which is the most
parsimonious tree?
