http://bioinf.ibun.unal.edu.co/cgi-bin/emboss/help/ffitch 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
WebWelcome to the Margoliash Lab. Neuroethology investigates nervous system function by relating it to innate and learned natural behaviors. It is distinguished from much of traditional neurobiology and psychology by being fundamentally centered in evolutionary biology, and by examining behavioral specialization across the breadth of the animal kingdom.
