DNA Testing establishes a person’s relationship with another. The Deoxyribonucleic Acid, abbreviated DNA, determines the genetic traits that can be inherited from a person. Except for identical twins, each person has his own DNA code unique only to him.

Establish Family Lineage

Paternity testing is done by finding association between the DNA profile of a parent and a child. Also, DNA helps in establishing family lineage, making it an important tool in family history research.

DNA testing can help determine if two people are related and descend from the same ancestor. It determines if two people having the same surname are related to each other. It also can provide clues on your ethnic origin. DNA test kits are now available which you can do at your own home.

Identify Hereditary Ailments

An unknown gene, or unit of heredity attached to the chromosomes which transmit hereditary character, can be identified by finding associations between DNA markers and the inheritance of a disease. Identifying hereditary ailments allows a person to take enough precaution to delay the onset of such diseases through change in lifestyle and proper health care. You can even avoid having a family with certain type of diseases by avoiding marriage or association with a person whose DNA marks exhibit such type of diseases.

Resolving Crime

Exposure to environmental abuse such as bacterial contamination does not destroy DNA. It does not degrade over time instead it is still a source of reliable information even from samples that are years old. This makes DNA testing reliable tool for solving crimes such as murders where criminals can be traced from even a single strand of hair or blood left at the crime scene.

Identification of missing soldiers in action is done through DNA testing on their skeletonized remains. This is also done identify missing people who were murdered and buried by their attackers.
