Your phylogenetic analysis resulted in 100 equally optimal trees and you would like to summarize the results showing only clades that are found in all trees. Therefore, you would use the: a. Majority rule consensus algorithm
b. Strict consensus algorithm
c. Adams consensus algorithm
d. The bootstrap algorithm

The correct answer is option B.

Explanation:

Strict consensus algorithm is the most restrictive approach that includes only that components that are shared by all the members of the group. In the strict consensus tree only those trees would be considered shared clades by all the trees.

The clades must be exact same or replicated in all the trees in this type of algorithm to analysis of the phylogenetic group. A 100% threshold in support leads to the Strict consensus trees algorithm.

Thus, the correct answer is : option B.

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
