Question 1

3. Know how to build and interpret an UPGMA phylogenetic tree from sequence divergence
   data

Answer 1

1. Divide closest by 2
2. FInd next closest, aerage distance between that and previous group (that’s your branch length- so .10+.15/2, then divide that by 2=bl)
3. Join groups by adding all comparisons, dividing by number of groups you’ve compared, then divide by 2

Question 2

4. Know how to compare mtDNA sequences in an alignment in order to determine sequence
   divergence
