All about DNA Tests and Applications.
Since the discovery of DNA testing some two decades ago, the popularity in use of the test has gone up significantly. 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. Blood typing was what was used in human identity testing before there was DNA testing. In comparison between blood typing and DNA testing, the latter has superseded the former because of being more accurate.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 when using DNA fingerprinting the loops and whorls are like a personal signature that only belongs to one person. 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 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.
With paternity tests, responsibilities that come with caring and providing for a child are, matched with the rightful persons. 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. Thanks to this use of DNA testing a child transitions easily to the new family.
