Fig. 3From: The ancestral chromosomes of Dromiciops gliroides (Microbiotheridae), and its bearings on the karyotypic evolution of American marsupialsPhylogenetic tree of American marsupials [30] depicting ancestral diploid number and ITS presence reconstruction. Branch colors indicate diploid number reconstructed with BayesTraits. Numbers above branches represent probability for each ancestor having ITSs. Cytogenetic data depicted at right follows: 1 = Sousa et al. [56]; 2 = Carvalho and Mattevi [12]; 3 = Svartman and Vianna-Morgante [13]; 4 = Pagnozzi et al. [15]; 5 = this study.
