Animals with a three-chambered heart would include Amphibians.
- Amphibians have three-chambered which comprises of two Atria and one ventricle. Examples of Amphibians include Frog, Toads, Salamanders.
- In Amphibians heart blood from the single ventricle travels to the lungs, skin, and body, where it is oxygenated. Before being pumped out of the heart, deoxygenated and oxygenated blood are mixed in the ventricle.
- This is because the Amphibians have low rate of metabolism and thus requires less oxygen for their metabolism.
- As a result heart's load to deliver oxygenated blood to body is lowered.
Thus, from the above pointers we can conclude that only Amphibians from the option have three-chambered heart.

Genotype. A human being's genome is made up of approximately 3 billion base pairs which make up about 2000 genes. Individuals, however, differ slightly in the sequence of their DNA in some regions. This unique genome identity is the indivudual genotype. Sequence of DNA in a genome can nowadays be determined through sequencing using Next Generation Sequencing machines
