DNA (deoxyribonucleic acid) testing became popular due to high-profile criminal investigations as well as in paternity cases. DNA is most commonly used in trying to prove the relationship of an individual to another person, that linking is aimed at trying to determine whether or not those two people are related or not.

DNA testing has also become a highly popular tool for determining a person’s ancestry. As DNA is passed down from one generation of your family to the next, there are some parts that still remain almost unchanged. This creates the highly unbreakable link between family generations and DNA testing helps when trying to reconstruct one’s family history. It can determine if you are related to the other person whom you have the test with and if you and that other person have a same ancestor. It will be provided with clues in regards to your ethnic origin.

There are now home DNA testing kits that can either be ordered through the mail or even over the Internet at prices less than $300. All you have to do is to obtain a sample of your cells through a cotton swab or through a mouthwash. Then you send those samples back to a lab for your DNA testing and wait for the results.

When it comes to DNA testing, one must be extremely patient waiting for the results – and whatever the result you get from your DNA test, just accept it as the tests are over 99% accurate.

Taking someone’s DNA without permission is illegal in a lot of countries.
