WebBranches show the path of transmission of genetic information from one generation to the next. Branch lengths indicate genetic change i.e. the longer the branch, the more genetic change (or divergence) has occurred. Typically we measure the extent of genetic change by estimating the average number of nucleotide or protein substitutions per site. WebJul 5, 2024 · While MPD is a measure of mean phylogenetic distance between all pairs of species in a sample, MNTD measures the average phylogenetic distance from each species to its closest relative. The former metric is sensitive to deep phylogenetic patterns, whereas the latter is more sensitive to terminal branching (Tucker et al., 2024). Both metrics are ...
