Topological inconsistency of the 102 NUTs compared with random trees of the same size. The NUTs are shown by red lines and ordered by increasing inconsistency score (IS) values. Grey lines show the IS values for the random trees corresponding to each of the NUTs. Each random tree had the same set of species as the corresponding NUT. The IS of each NUT was calculated using as the reference all 102 NUTs and the IS of each random tree was calculated using as the reference all 102 random trees. Also shown are the IS values obtained for those partitions of each NUT that were supported by bootstrap values greater than 70% or less than 90%.
