Presentation Transcript

  1. 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?

  4. 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
