Since the discovery of DNA, there have been many applications developed for its use. From paternity tests, the identification of criminals, and helping to establish a person’s family history, the uses of DNA testing are wide-ranging.
With recent advancements in the field of DNA testing, the accuracy and data that can be achieved have only gone on to increase the applications for that DNA tests can be used for. Read on to learn more about the common uses for DNA testing.
1. Archeology and Anthropology
With the ability to test bone fragments and other remains of animals that are found, DNA has proven to be the perfect tool to reference and compare the species that are found through archeological digs. This means that we are now able to track the genetic mutations that a species undergoes to track and prove evolution. This can give great insights into the origin and migration of not only animals but also human beings.
2. Paternity tests
This is an ironclad method of establishing the paternity of a child. This can be either to give each parent the peace of mind that they need if there is confusion, or it can be for legal reasons. This type of DNA testing can even be done before a baby is born.
3. To establish a family history
DNA tests have recently become commercially available to the general public. Never before have we have the ability to submit a small sample of saliva and learn so much about ourselves and our family history. This data can go a long way to providing clues to helping someone when they would otherwise have run out of leads on their genealogical trail.
4. Predisposition to disease
DNA tests can let someone know if they have a higher chance of developing certain health problems. This can be a literal lifesaver as it can encourage them to visit the doctor on a more regular basis and insist on check-ups. It can also alert them to any preventative measures that they should consider taking. This type of DNA testing can be performed while a baby is still in the womb.
5. Criminal identification
DNA tests are very commonly used to identify criminals. Everything from new cases where there was very little other evidence to old cases that have since been reopened. The application of DNA testing into the justice system has proven to be groundbreaking. Just don’t believe everything that you see on TV as there is a lot more to it than they make out.
6. Reuniting family members
Tracking down long-lost relatives can be done through DNA testing. This can be very important for families that have become separated. The best part is that the DNA can be several generations removed. So, if the member of the family is deceased, a match can still be found through siblings, grandparents, or children.
7. They’re fun!
It can be really exciting to find out something about your ancestors that you didn’t know. With something as simple as sending off your saliva to get DNA tested you might find some really shocking things about your past. You might even re-write your family’s history. Many of those who take the DNA test are thrilled by the results and can’t wait to share them with family and friends. The DNA testing kits also make for an excellent gift as you are giving the recipient an insight into their past that was not available to them a few years ago.
