Webmethod, Fitch-Margoliash method, Cavalli-Sforza method, neighbor-joining method, UPGMA method. All ve methods were able to reconstruct the true phylogeny. Leitner et al. (1996) collected HIV samples from people with known epidemiological relationships, and tested with various reconstruction methods.
The Fitch–Margoliash method uses a weighted least squares method for clustering based on genetic distance. Closely related sequences are given more weight in the tree construction process to correct for the increased inaccuracy in measuring distances between distantly related sequences. See more Distance matrices are used in phylogeny as non-parametric distance methods and were originally applied to phenetic data using a matrix of pairwise distances. These distances are then reconciled to produce a tree (a See more Distance-matrix methods of phylogenetic analysis explicitly rely on a measure of "genetic distance" between the sequences being classified, and therefore they require an MSA (multiple … See more • List of phylogenetics software See more WebAbout Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators ...
