Genetics, study of heredity in general and of genes in particular. Genetics forms one of the central pillars of biology and overlaps with many other areas, such as agriculture, medicine, and biotechnology. Learn more about the history, biology, areas of study, and methods of genetics.

What Is Genetics? - National Institute of General Medical Sciences
Genetics is the study of genes and heredity—how traits are passed from parents to children through DNA. A gene is a segment of DNA that contains instructions for building one or more molecules that help the body work.

What Is Genetics? Genes, DNA, and Inherited Traits
Genetics is the study of how living organisms inherit traits from their parents through DNA, the molecule that stores biological instructions in nearly every cell of your body.

Genes are specific sections of DNA that have instructions for making proteins. Proteins make up most of the parts of your body and make your body work the right way. You have two copies of every gene. You inherit one copy from your father and one copy from your mother.
