Molecular phylogeny is how the molecular structures are used for gaining data or information about the evolutionary relationship of an organism.One of the most common approaches, in this case, is how homologous genetic sequences are compared by using a sequence alignment process.It helps to identify a similarity which will cover T-Coffee and Clustal W. Mitochondrial DNA data is used by molecular phylogeny for building a “relationship tree” which shows the entire evolution of different organisms.
