Fundamentally, DNA molecules bear genetic codes and affect the traits of a person beginning from the color of the eyes to a number of personality aspects. All body cells starting from the blood to bones, skin up to the heart have an entire set of such molecules. For DNA test locations nonetheless, tests are undertaken for reasons of identification in cases like parental testing, genetic genealogy, forensic testing or even 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.
It is only for identical twins where you can find similar genetic markers. In DNA testing, however, the crucial thing is the way of looking at genetic markers, which give the significant differences or similarities in numerous letters in a genetic code. In genetic, forensic or parental testing, checks for similarities in the two given biological samples are undertaken for the genetic markers.
Since all cells in every part of the body have exactly the same genetic composition, the sample to be tested can be taken from almost anywhere in the body. This may include skin, blood, hair follicles and other body fluids. For instance, a forensic scientist can compare genetic composition from skin cell of the fingernails of crime victim to those from a blood sample obtained 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 a bid to lessen the chances of error, scientists undertake further tests to the genetic marker. The more similar a genetic marker produces from the sample the more the accuracy levels of the test. Nevertheless, it is costly and takes a lot more time in testing additional markers. The likelihood of two people who are unrelated to have a similar profile is smaller 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.
Normally, prior to any genetic test, it is imperative that an individual comprehends the procedure, its limitations, and benefits as well as any possible consequences from the results. The process of educating a person about the test on top of getting their permission is called the informed consent.
