What are the chemical factors that determine traits known as?

• A. Alleles
• B. Chromosomes
• C. Genes
• D. Phenotypes

Answer: (C)

The term that refers to the chemical factors determining traits is genes. Genes are segments of DNA that carry the instructions for the development and functioning of all living organisms. They play a crucial role in determining specific characteristics by encoding the information necessary for the synthesis of proteins, which ultimately influence traits and various biological functions.

While chromosomes are structures within cells that contain a person’s genes, they do not specifically describe the individual chemical factors themselves. Alleles are variations of a gene that can lead to different expressions of a trait but are part of the broader category of genes. Phenotypes refer to the observable characteristics or traits resulting from the interaction of an individual’s genotype (which consists of their genes) and the environment. Therefore, the most accurate term associated with the underlying chemical factors that influence traits is genes.
