Genetic

Genetic refers to the genes or heredity in living organisms. It is the study of genes, genetic variation, and heredity in organisms. It is generally considered a field of biology, but it intersects frequently with many of the life sciences and is strongly linked with the study of information systems.

Overview

The study of genetics is important as it gives us a fresh look at how to cure or prevent diseases. The concept of genetics allows us to know how life evolved and will continue to evolve. The more we study genetics, the more we realize that we are able to manipulate genes in order to enhance our health and well-being.

History

The history of genetics dates back to the ancient Greeks with hypotheses about factors that contribute to the physical differences that are observed among different individuals. Modern genetics started with Gregor Johann Mendel, a late 19th-century scientist and Augustinian friar. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring.

Genetic Disorders

Genetic disorders are diseases that are caused by abnormalities in an individual's genetic material. These disorders are present from birth, and can cause a range of health problems, from mild conditions to severe illnesses. Some genetic disorders are inherited from the parents, while others are caused by acquired changes or mutations in a preexisting gene or group of genes.

Genetic Testing

Genetic testing is a type of medical test that identifies changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person's chance of developing or passing on a genetic disorder.
