He saw that not only was there yellow seeded pea plants, but green seeded pea plants. Recessive traits that seemed to have disappeared in the first cross reappeared here.
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.
