From: Phylogenomic analyses reveal a molecular signature linked to subterranean adaptation in rodents

Box plots that show the GC content (GC) and GC content at the third codon position (GC3) for subterranean rodent lineages (the blind mole rat, BMR and naked mole rat, NMR) and their non-subterranean relatives (the mouse and guinea pig)
