Figure 4. Evolution of the Mitochondrial Genetic Code in Arthropods.

Figure 4

This figure merges two independent most-parsimonious ancestral character state reconstructions: the presence (transparent) or absence (light grey) of the AGG codon, and the predicted translation of AGG as Lys (purple) or Ser (yellow). Species in which AGG was not predicted and species in which we determined that the assignment was unreliable (nodes without a rectangle) were treated as ambiguous states. The number of AGG codons, and the anticodons of tRNA-Lys and tRNA-Ser are indicated next to the species name.
