What does a bootstrapping value of 100 mean on a phylogenetic tree node?
In a phylogenetic tree, a bootstrap value is a measure of the statistical support for a particular node. It is calculated by resampling the data and building a new tree for each resample. The bootstrap value for a node is the percentage of trees in which that node appears.
A bootstrap value of 100 means that the node appeared in all of the resampled trees. This indicates that the node is strongly supported by the data and that it is likely to represent a true evolutionary relationship.
