WebPERFORMANCE OF THE MAXIMUM LIKELIHOOD, NEIGHBOR JOINING, AND MAXIMUM PARSIMONY METHODS WHEN SEQUENCE SITES ARE NOT … WebExplanation: The neighbor-joining method is very much like the Fitch-Margoliash method except that the choice as to which sequences to pair is determined by a different algorithm. In the situation mentioned in option d, the neighbor-joining method and the Sattath and Taversky method, are the most reliable in predicting the correct tree.
WebJan 1, 2000 · Compared with maximum-likelihood phylogeny reconstruction, Weighbor is much faster, while building trees that are qualitatively and quantitatively similar. Weighbor appears to be relatively immune to the “long branches attract” and “long branch distracts” drawbacks observed with neighbor joining, BIONJ, and parsimony.
