Genetics is the study of genes, genetic variation, and heredity in living organisms. It is generally considered a field of biology, but intersects frequently with many other life sciences and is strongly linked with the study of information systems. Genetics is the science of genes and how traits are passed on from one generation to the next.
Genetics studies how genes and groups of genes are involved in health and disease. It can also help improve disease diagnosis and treatment. Almost every human trait and disease has a genetic component. Genes are sections of DNA (deoxyribonucleic acid) that are found inside every human cell. Genes carry information that gets passed from one generation to the next. For example, genes determine why some illnesses run in families and whether babies will be male or female. Genetics has given rise to a number of subfields, including molecular genetics, epigenetics, and population genetics.
