The section of DNA that governs physical and behavioral traits is called a gene. Genes are the basic units of heredity and are responsible for encoding the instructions that determine the traits and characteristics of an organism. These instructions are used by cells to produce specific proteins, which in turn influence the physical and behavioral traits of an individual. To identify a gene related to a specific trait, scientists utilize various techniques like genome sequencing, genetic mapping, and studying the inheritance patterns of traits within families.
