Bootstrapping values in phylogenetic tree
Webcharacters. Bootstrapping calculates a support value for each node based on the fraction of samples that support that node. The highest support value is 100, while values below 70 are usually considered weak. Values below 50 aren’t shown; in fact, branches below 50 are collapsed and shown as a polytomy. WebTypically you will see bootstrap (or other confidence estimate) values shown on a phylogeny. For example in the left-hand tree in Figure 11, bootstrap values are shown from 100 replicates. Sometimes asterisks …

WebAs a general rule, if the bootstrap value for a given interior branch is 95% or higher, then the topology at that branch is considered "correct". See Nei and Kumar (2000) (chapter 9) for further details. This test is available for four different methods: Neighbor Joining, Minimum Evolution, Maximum Parsimony, and UPGMA.
