Consensus tree obtained from the Bayesian analysis of concatenated data based on partial sequences of the Arg-K, Opsin, EF1-α, 28S and 16S genes from Meliponini and Bombini species, and ancestral chromosome number inference as implemented in Mesquite by MP analysis.
The squares in the terminal branches and the color of the branches represent the different haploid numbers, and the ancestor nodes indicate the ancestral states estimated to be the most parsimonious.

Consensus tree obtained from the Bayesian analysis of concatenated data based on partial sequences of the Arg-K, Opsin, EF1-α, 28S and 16S genes from Meliponini and Bombini species, and ancestral chromosome number inference as implemented in Mesquite by ML analysis.
The squares in the terminal branches and the color of the branches represent the different haploid numbers, and the ancestor nodes indicate the most likely ancestral state. Pie charts indicate the probabilities of each ancestral state.

Consensus tree obtained from the Bayesian analysis of concatenated data based on partial sequences of the Arg-K, Opsin, EF1-α, 28S and 16S genes from Meliponini and Bombini species, including ancestral haploid chromosome state reconstruction inferred under Bayesian and Maximum Likelihood optimizations in Chromevol 2.0 software.
Pie charts at nodes represent the inferred chromosome number in both Maximum Likelihood optimization and the first data for Bayesian optimization and its Bayesian posterior probabilities.
