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.
Generally, there will be 99.9% similarities in the DNAs from two different individuals. Nevertheless, the 0.1% code sequence molecules that vary from person to person create their uniqueness. Such sequencing is referred to as genetic markers that forensic scientists usually use as a component of the code when undertaking the tests. Nonetheless, the closely related persons are the high likely to have some identical genetic markers.
It is only in identical twins that you will find the same genetic markers. However, in DNA testing, the most important thing is how to look for the genetic markers that gives the important similarities or differences in the billions of letters of genetic code. In parental, genetic or forensic testing, they check for similarities between the two biological samples in 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.
