Heredity refers to the passing of characteristics from parents to offspring through the transmission of genetic information.
Genes are the basic units of heredity, carrying information from one generation to the next.

Evolution refers to the gradual change of species over time through the process of natural selection, genetic drift, mutation, and gene flow.

Genes code for specific proteins, which determine the development, growth, and function of an organism.
Genes also regulate the expression of traits, such as eye color, hair color, and height.
