If you have one tree that hypothesizes that A and B are more closely related to each other than either is to C (Fig. ) and two trees that hypothesize that B and C are more closely related to each other than either is to A (Fig. , c), then the majority consensus tree will have the latter topology (Fig. ). If there is an "even vote," then the result is a polytomy. If the trees are logically consistent, then the most resolved tree is preferred (just as in the case of Adams consensus trees).
