What do genes provide for the body?

• A. The instructions to build the body
• B. Only color of eyes
• C. Only hair type
• D. No influence

Answer: (A)

Genes provide the instructions to build the body. They are units of heredity made of DNA that carry the code for making proteins and regulating when and how cells grow and specialize. This genetic blueprint guides the development of tissues and organs, shaping the body's structure and function. Traits like eye color or hair type arise from how genes are expressed, but those are specific outcomes of the broader instruction set. There is clear influence from genes across many aspects of biology, not zero influence.
