The average bootstrap probability for these edges was 90 ± 14%, i.e. most edges were inferred with high stability.
Bootstrap probabilities for major clusters are shown by percentages.
Third, JMATING also provides the bootstrap probability for rejecting the null hypothesis.
Reliability of the resulting tree topology was tested by the bootstrap method [ 28] (at 1000 pseudoreplicates) which generated the bootstrap probability for each interior branch in the tree.
The bootstrap probability for each node was calculated by generating 1000 bootstrap replicates.
However, there is strong support (98% bootstrap probability) for a sister group relation between brachiopods and annelids in the tree based on the nucleotide data set.
We computed approximate bootstrap probabilities (BP) for individual tree topologies with resampling of estimated log-likelihoods (RELL) [ 34] with CONSEL [ 26].
The numbers at nodes indicate bootstrap probabilities with 100 replicates for the ML and NJ methods, in order.
Although the ML analyses suggest an origin of acanthopterygian pax6a and -6b genes through the TSGD (fig. 2 B), the support for this duplication node (bootstrap probability in the ML analysis, 18) is poor.
However, the statistical support for this grouping is low (bootstrap probability in the ML analysis, 49).
