Common interval analysis presented on the most supported Bayesian tree, obtained from dataset “B”, where each tip represents a unique gene order. Internal nodes are named as “An”, where “n” is a number between 0 and 7, and represents ancestral gene orders. C and P indicate consistency and parsimony values, respectively. The colors code consistent (green; highest level of certainty), k-consistent (yellow; intermediate level of certainty) and inconsistent (red; low level of certainty) nodes. Mutation types are indicated on corresponding branches, T: transposition, TDRL: tandem duplication and random loss
