Bootstrapping in MEGA:
Open the file Crab_rRNA.meg Select Phylogeny > Neighbor-Joining -> Bootstrapping can be done for each method
2
Bootstrap values are presented for internal branches
3
Construct a NJ tree with bootstrap values for the cytochrome c oxidase subunit II protein sequences in cyt2.fas Who is the closest relative of humans? How confident are you at this result?

Construct a NJ tree with bootstrap values for the cytochrome c oxidase subunit II protein sequences in cyt2.fas Who is the closest relative of humans? How confident are you at this result?
5
Consensus Implementation of the consensus program in Mega.
Use the flu.fas data from class 7 and build a maximum parsimony tree.
6
How many different trees can be found using maximum parsimony?
7
Given the consensus tree found when using a 30% cutoff do you expect something to change if we use a 100% cutoff ?
8
100% cutoff
9
30% cutoff
