Traits or physical characteristics are represented by ____________.
Answer:
Traits or physical characteristics are represented by genes.
Explanation:
Genes are segments of DNA that contain instructions for the development and functioning of living organisms. They determine various traits, such as hair color, eye color, height, and many other physical and behavioral characteristics.
Each gene carries the information for a specific trait, and individuals inherit genes from their parents. The combination of genes inherited from both parents determines the traits and physical characteristics that an individual will have.
It's important to note that while genes play a significant role in determining traits, they can also interact with environmental factors to influence the expression of those traits. This field of study is known as genetics, which explores how genes and the environment interact to shape an individual's characteristics.
