By looking at the genes of some animals we can determine which living species are most closely related to each other. This also reveals which species most recently diverged from their common ancestor. Based on the partial gene segments shown, which pair of animals are genetically most closely related and therefore most recently diverged from their common ancestor?

• Chimpanzee and Mouse

• Rat and Mouse

• Rat and Chimpanzee
