Final answer:
Chromosomes contain stretches of DNA called genes, which control individual traits. Each gene typically encodes the instructions for one protein and determines characteristics such as hair color. the correct answer to the question is A) Genes.
Step-by-step explanation:
Chromosomes contain stretches of DNA called genes, which contain the information that controls particular traits for an individual. A chromosome may contain tens of thousands of genes. Most genes contain the instructions for a single protein.
Genes determine specific characteristics by coding for specific proteins, and traits are the different forms of a characteristic. For instance, hair color is a characteristic, while blonde, brown, or black are the traits determined by the genes coding for hair color. So, the correct answer to the question is A) Genes.
