Genetics is the study of heredity.

• A. The study of heredity.
• B. The study of ecosystems.
• C. The study of metabolism.
• D. The study of planetary motion.

Answer: (A)

Genetics is the study of heredity—the transmission of traits from parents to offspring through genes and alleles, and how these patterns of inheritance create variation in populations. This field asks how traits are passed on, how dominant and recessive alleles interact, and how genetic mechanisms shape inheritance across generations. The other areas describe very different disciplines: ecology studies interactions within ecosystems, metabolism looks at chemical processes inside organisms, and planetary motion belongs to physics/astronomy. Because genetics focuses specifically on heredity and how traits are inherited, it is the best fit.
