(a, b) The two most parsimonious trees (L=48) retrieved from our cladistic analysis of chromosomal characters in West African Taterillus, and (c) their consensus tree. The polarization of each character changes were assessed a posteriori using outgroup comparison. Gray circles, balck losanges, white blocks and gray triangles represent Robertsonian fusions, centric fissions, tandem fusions and pericentric inversions, repsectively. Close and open circles above these symbols correspond to convergent and reversal events, respectively. Bootstrap and decay index values are indicated above and below the branches of the consensus tree, respectively.
