Evaluation of the performance of data partitions in the combined maximum-parsimony tree. The analysis was limited to the 28 terminals, represented by all seven data partitions [see Additional File 4]. Bootstrap values are above the branches (only higher than 50%); partitioned Bremer support (PBS) values under the branches: COMB (total Bremer support of all partitions), MOR (PBS of morphology), MOL (total Bremer support of the six molecular partitions). The support grids: black cells: PBS > 0; white cells: PBS < 0; diagonal: PBS = 0. For color code see Figure 2.
