Given the DNA sequence matrix below:
Fern AGCCCAGGCTTCGAATGTCC
Pine AGCTTCAGTGTCGCACTTCC
Oak AGCTTCAGCGTCACACATCC
Moss AACCTTGGTGTCAAACGTCC
1. Assuming that Moss is the outgroup, draw all three possibletrees of evolutionary
relationships among these species. Label your trees A, B, andC.
2. Sum up the number of differences between the DNA sequences forall pairs of species
(There are 6 total pairs of species to be compared). Based on thesevalues, which tree (A,
B, or C) do you think is best under the Genetic Distancecriterion?
3. Determine the minimum number of mutations required under theparsimony criterion for
each of the three trees. Which is the most parsimonious tree?
