Question

Can someone walk me through this problem?

Outgroup Corn Soybean Wheat Determine which tree of yours is most parsimonious. Using the RUBISCO DNA information in the table below map the changes onto the trees as was demonstrated in the PowerPoint. Conduct a parsimony analysis (looking for the tree with the least steps) and calculate the score for each tree. Which of the trees is most parsimonious given the known DNA data below? Annotate this in your Individual Deliverable Google doc (Step 4 under the Individual Activity 2).

Answer 1

Soyabean wheat 6,7,8 corn 2,3 outgroup soyabean corn wheat outgroup 2,3,10 6,8,10,7 Changes at site 1,3,4,6,7,8,9,10 Changes at site 1,3,4,9,10 Tree A Tree B

tree A has 14 site changes whereas tree B has 11 site changes.

tree B is more parsimonous than tree A

corn and wheat are more closely related as they show difference at only two sites.
