DNA Testing.

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. 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 In comparison between blood typing and DNA testing, the latter has superseded the former because of being more accurate.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 is based on a comparison of DNA features that will never be similar to another set between two people not even identical twins.

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. 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 largely applied in criminal applications but there are non-criminal applications as well.

There is a big difference between the use of DNA testing in criminal and civil applications. In civil cases the testing of the DNA is done to determine the relationship between two individuals while in criminal application the test will be used to match the evidence that has been collected at the crime scene. Immigration and child support cases make use Of DNA testing , they make up most of the civil uses of the cases. In an event where documentary evidence is not clear enough on relationship between two individuals, DNA tests will be used as the ultimate test to clear all doubts.

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. With a DNA test it will aid in adopting a child into a family that has a similar ethnic background. This helps in establishing child with a family that is the best fit for them. The transition of the child to the new family will be easy this way.
