Which statement about the Human Genome is correct?

• A. It determines only height
• B. It determines only eye color
• C. It determines every characteristic in the human body, from eye color to vulnerability to disease
• D. It determines only blood type

Answer: (C)

The genome contains the instructions that influence virtually all heritable traits and disease risk. It provides the blueprint for making proteins and regulating development, which shapes features from eye color to how susceptible we are to certain illnesses. That broad influence is why this statement fits best: the genome helps determine a wide range of characteristics, not just a single trait. While environment and other factors can modify how traits are expressed, the genome underpins the majority of inherited features, which is why saying it determines everything from eye color to disease vulnerability is the most accurate among the options.
