medicine agriculture science of force and motion science of heredity and variation
I gave my students this multiple choice question: In the 17th century, Gregor Mendel crossed pea plants with different traits and observed the results in their offspring. To which of these did Mendel contribute most directly with his work?

Only one answer is correct among these 4 choices:
- medicine
- agriculture
- science of force and motion
- science of heredity and variation

Could you tell me which one is correct?

science of heredity and variation
