The Role of DNA Tests.
DNA testing has become very common today despite being discovered not long ago, its use in the criminal justice system and other fields has made identification of persons very easy. With a simple DNA test it’s easy to reveal whether two people are related and what the nature of their relationship is like. In the next couple of years a strand of hair will not only tell the identity of the person but it will also narrow down to the age of the person as well. Before the discovery was introduced human identity was determined through blood typing. In comparison between blood typing and DNA testing, the latter has superseded the former because of being more accurate. DNA testing relies on the comparison of two specific DNA features that are known as DNA markers.
Even with DNA fingerprinting there is a comparison of loops and whorls which are very unique to an individual. In DNA testing if the samples’ patterns are identical then they are likely to be from the same person. Even if profiles prove to be different but similarities can be observed in the samples then it proves that there is a high chance that the people are related. The degree of similarity points out to the degree of relatedness as well. DNA testing is mainly applied in the fight against crime but there are non-criminal applications too.
There is a big difference between the use of DNA testing in criminal and civil applications. Criminal application is all about matching samples from suspects to that of the sample that has been collected at the scene while with civil application it is predominantly determining the relationship between two people. In legal non-criminal cases DNA testing is applied to help in determining child support cases and immigration as well. In most cases where there is no documentary evidence lacks the use of DNA evidence is used to clear doubts as that is evidence enough to both parties that are on opposites.
Thanks to paternity tests children are provided for in cases where people would have otherwise abandoned what is their responsibility. In child adoption DNA testing is applied and many people might question how that work being that there is no relation between the adopting party and the child. Once the ethnic background of the child has been matched with an adopting family adoption process can begin. This helps in establishing child with a family that is the best fit for them. Transition for the child and the family will also be easy.
