What is the difference between using an optimality criterion and a clustering algorithm for reconstructing phylogenetic trees? a. In the steps necessary to reconstruct a phylogenetic tree, the optimality criterion must be applied first in order to provide valid input data for the clustering algorithm
b. In the steps necessary to reconstructing a phylogenetic tree, the clustering algorithm must be applied first in order to provide valid input data for the optimality criterion method
c. Clustering algorithms function by determining the number of steps necessary to transform one tree into another, while optimality criterions function by determining the number of steps necessary to transform one tree into another
d. Optimality criterions function by determining the number of steps necessary to transform one tree into another, while clustering algorithms function by create hereditary groupings

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).
