What is a gene?

A gene is the basic unit of heredity that carries information from parents to offspring and determines specific traits.

Genes are made up of DNA and are located on chromosomes within the nucleus of a cell. Each gene contains instructions for the production of proteins, which control various functions and characteristics of an organism.

For example, genes influence traits such as eye color, height, and blood type.

Genes play a crucial role in inheritance, as they are passed from one generation to the next and help define the biological identity of an organism.
