Which field studies how qualities of living things are transmitted through genes?

• A. Geography
• B. Chemistry
• C. Genetics
• D. Astronomy

Answer: (C)

Genetics is the field of study that focuses on how qualities, traits, and characteristics of living organisms are passed down from one generation to the next through genes. It explores the molecular structure and function of genes, variation of inherited traits, and genetic sequences that influence biological processes. By studying genetics, researchers can understand inheritance patterns, genetic disorders, and the role of DNA in the development of living organisms. This field is fundamental to many aspects of biology and medicine, including evolution, heredity, and the biological basis of behavior.

Other fields, such as geography, chemistry, and astronomy, do not directly address the transmission of traits through genes. Geography deals with the physical features of the Earth and the distribution of life across it. Chemistry focuses on the composition, structure, and properties of substances, while astronomy studies celestial objects and the universe as a whole. Thus, genetics is specifically concerned with the hereditary mechanisms that shape living organisms, making it the correct choice.
