Differential Evolutionary Constraints in the Evolution of Chemoreceptors: A Murine and Human Case Study
Figure 6
Reconstructed phylogenetic tree of the chemoreceptor families. Each square represents a CR gene. Blue, red, and green squares represent Rattus norvegicus, Mus musculus, and Homo sapiens genes, respectively. Phylogenetic trees were reconstructed with Tamura-Nei model. T1R: type I taste receptors; T2R: type II taste receptors; VN: vomeronasal receptors.
