Molecular phylogenetics /mÉµËlÉkjÊlÉr ËfaÉªlÉµdÊÉ¨ËnÉtÉ¨ks/ is the branch of phylogeny that analyses hereditary molecular differences, mainly in DNA sequences, to gain information on an organism's evolutionary relationships. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree.Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography.olecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography.
Reading phylogenetic trees: A quick review (Adapted from evolution.berkeley.edu) â¢ A phylogeny, or species/evolutionary tree, represents the evolutionary relationships among a set of organisms or groups of organisms, called taxa (singular: taxon) that are believed to have a common ancestor.ypes of Biological trees â¢ Taxonomy trees, like the one hosted at NCBI, are hierarchies; thus classification is determined by position or rank within the hierarchy. It goes from kingdom to species.â¢ Phylogenetic trees represent evolutionary relationships, or genealogy, among species.
