Building Distance Trees in MEGA

  • Once a distance matrix is calculated the distances may be used to build a tree.
  • The "Phylogeny" option provides three choices for distance-based trees: UPGMA, Neighbor-Joining, and Minimum Evolution.
  • (A parsimony option is also available; we will build a parsimony tree when we get to the PHYLIP package).

  • Below are the results using the Minimum Evolution method.
  • The 0.02 scale implies 0.02 substitutions/site.
