DNA testing has rose in popularity since it began to be used, most of the application has been in criminal justice system among others. A DNA test will reveal whether two people are related and what their relationship is. With a single strand of hair and another match to run the test against , one can determine the identity of a person and from how things are advancing quickly it is a matter of time till people can narrow down to the age of a person. 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 In comparison between blood typing and DNA testing, the latter has superseded the former because of being more accurate.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 works by comparing two DNA features that are known as DNA markers because each person has very unique ones.
DNA fingerprinting also uses almost the same concept as it compares the whorls and the loops in the fingerprints of the individual that are unique to that individual. In a test there will be a sample with which the test is being run against, if the patterns in the sample and the test prove to be identical then they are likely to be from the same person. Profiles, may be different but if there are big similarities being observed then it’s most likely that they are from the same person. When it comes to determining the results, the degree similarity in the samples suggest the degree of relatedness as well. DNA testing is largely applied in criminal applications but there are non-criminal applications as well.
If you seek to understand the two applications of DNA testing you will discover that there is a significant difference between the two. 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.
With paternity tests, responsibilities that come with caring and providing for a child are, matched with the rightful persons. In adoption of children as well some countries will require the use of DNA tests but if you are new to that you might wonder just how a paternity will aid in subjects that are not related at all. Here the tests will be used to match the child’s ethnic background to that of the person that is hoping to adopt. It aids in fitting a child with the best family fit. Transition for the child and the family will also be easy.
