DNA molecules carry the genetic code as well as influence our traits beginning from eye color to different personality aspects. In fact, each body cell beginning from blood to bone, skin to the heart has a whole set of these molecules. Nevertheless, at DNA test locations, tests are used for the purposes of identification for cases such as parental testing, forensic testing, genetic genealogy as well as gene therapy.
Usually, 99.9% of the DNAs from two different people will be identical. However, the 0.1% molecule code sequence that varies from one person to another is what creates the uniqueness. Such sequences are known as genetic markers and forensic scientists normally use that part of the code when carrying out the test. Nevertheless, the more closely related individuals are, the highly likely that some genetic markers will be identical.
Usually, only identical twins may have genetic markers that are alike. Nonetheless, DNA testing looks at these genetic markers as the crucial items that give a significant similarity or difference in the abundant letters contained in the genetic code. In forensic, parental or genetic testing, checks on the similarities of two sets of biological samples can be undertaken for their genetic markers.
Since every cell from each part of our body bear the exact similar genetic composition, the samples to be tested may be withdrawn from almost any part of the body. This can include the blood, skin, hair follicles or even the other body fluids. For example, forensic scientists may compare the genetic composition of the skin cells from the fingernails of a crime victim against the ones from a sample of blood got from a suspect.
The correctness of experiments on genetics has enormous implications. The test at times become the simple evidence of proving an involvement in crime for a suspect or even releases a person who is facing wrong convictions. In fact, it becomes easy to see the genetic make-up of two different biological samples. On top of this, a match never confirms that samples were taken from a particular person because there is a slim possibility of genetic markers in two people being similar especially when they have a blood relation.
In order to reduce the chance of an error, scientists perform more than one testing on the genetic marker. The more similar genetic markers there are in the samples the higher the level of accuracy in the tests. However, it takes more time to test more markers and is usually more expensive. The likelihood that two unrelated people could have similar profiles is less than one in a billion.
Paternity genetic testing result can be used as legal evidence for parental rights, child support, social benefits, inheritance claims, adoption and the likes in case a proof of blood relationship is needed. Currently, genetic testing is the most accurate family relationship or paternity testing method available.
Usually, before carrying out any genetic tests, it is essential that people get to know the procedure, the benefits as well as the limitations and any other possible consequences the results pose. The process in which individuals are educated concerning these test and getting their permission is termed informed consent.
