FIGURE 4 in Reassessing the causal connection between satDNA dynamics and chromosomal evolution in Ctenomys (Rodentia, Ctenomyidae): Unveiling the overlooked importance of the Y chromosome

FIGURE 4 Ancestral reconstruction of diploid numbers (2n) and main RPCS reductions and amplifications in the Ctenomys Corrientes group. Ancestral diploid numbers were inferred with the ChromEvol model implemented in RevBayes, over the mtDNA Bayesian phylogeny of the Corrientes group. Numbers in internal nodes/ terminals represent inferred/observed 2n. Colored circles depict 2n (size) and posterior probability of the inferred value (color). Red and green branches depict significant reductions and amplifications in diploid numbers, respectively. Smaller equal-sized black circles show well-supported nodes (posterior probability> 0.75). Black arrowheads denote a marked increase/decrease in RPCS copy numbers (inferred from females). The scale bar is expressed in substitutions per site.
