WebMar 17, 2024 · According to these di↵erences, biological phylogenetic trees may be classified into three categories: Cladogram: gives no meaning to branch lengths; only the sequence and topology of the branching matters. Phylogram: Branch lengths are directly related to the amount of genetic change. Molecular phylogenetics is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader t…

WebBayesian inference of phylogeny combines the information in the prior and in the data likelihood to create the so-called posterior probability of trees, which is the probability that the tree is correct given the data, the prior and the likelihood model.

Different genes change evolutionarily at different rates and this affects the level at which they are useful at identifying relationships.
