Consistency index phylogeny
Read and analyze a phylogenetic tree that documents evolutionary relationships. This bee and Echinacea flower (Figure 1) could not look more different, yet they are related, as are all living organisms on Earth. By following pathways of similarities and changes—both visible and genetic—scientists seek to map the evolutionary past of how life developed from …Sep 11, 2019 · Consistency index or relative consistency is the liquid limit of the soil, minus the natural moisture content, divided by the PI. It is related to the LI and is an indicator of the relative shear strength. As CI increases, the firmness, or shear strength of the soil also increases. It corresponds to the ratio of the consistency index to the number of steps in a given tree. For example, if the most parsimonious phylogeny has 88 steps, the consistency index will be equal to 1. If another phylogeny based on the same database presents 100 steps, then its consistency index will be 88/100, that is, 0.88 . The method is a good ...

The Consistency Index is equal to one if there is no homoplasy. And the Retention Index is defined as. RI = \frac {MaxChanges - ObsChanges} {MaxChanges - MinChanges} RI = M axChanges−M inChangesM axChanges− ...
This ensures consistency between data and phylogeny only for the variables that are being used in the model (set by 'formula'). If phy is a 'multiphylo' object, all phylogenies will be cropped to match data. But the dataset order will only match the first tree provided. The returned phylogeny will be a 'multiphylo' object.Parameters for the ITS phylogenetic tree are as follows: tree length (TL) = 133, consistency index (CI) = 0.985, retention index (RI) = 0.994, relative consistency index (RC) = 0.979, and ...Sep 29, 2008 · TNT is a fully interactive program. All versions (Windows, Linux and Macintosh) can be run by means of commands. In addition, the Windows version has a sophisticated menu interface or GUI ( 1 - 5 ), which makes TNT the only major phylogeny program that can be menu-driven under Windows. Using emulators or alternative implementations of the ... ….

The index therefore runs from 0 to 1.
