With the evolution of science as a full-fledged discipline, many new inventions are being made to make some of the biological tests and examinations easier to be conducted. DNA samples that are present within the human body serve to be the best source to find out the biological base of a particular relationship. Among several techniques that have come into emergence in recent times, one is the DNA relationship testing. This is the form of examination through which the facts and truths behind the relationship between two or more people could easily be put forth. DNA paternity tests are among the other forms of relationship testing, using which you can easily find out whether a father-son relationship has a biological base.
Prior to utilizing the DNA paternity testing techniques, the early people tried to find out the resemblances between a child and his suspected father. In case, the behavioral pattern and facial expressions of both the two seemed to be similar, they were declared to have a true father-son relationship. Later on, they matched the color of the eyelids of the child and suspected father. The matching of the eyelid color was the proof of their genuine relationship. But do you think the result obtained through these means were accurate? Not really. The DNA relationship testing, therefore, has come up with advance tools and techniques to help people find out the relationship truths with accuracy to maximum possible extent.
The DNA pattern that is found in an individual's body is inherited from his or her biological parents, which is similar to their genetic code and molecular structure. Thus, the DNA particles that are found in one's body are completely unique and do not show any resemblance with anyone else. This similarity helps in determining the biological basis of a father-child relationship with the help of their deoxyribonucleic acid or DNA samples. This is the reason that makes DNA paternity test one of the most preferable means of testing the paternity of a person. The DNA relationship testing, however, is not only used to determine the father-child relationships, but also enables one to find out the relationships between the siblings.
There are many forms of technique that are used for DNA paternity testing. Earlier, the ABO Blood Group Typing and Human Leukocyte Antigens or HLA testing was utilized. While in recent times, two methods are generally seen to be used majorly, namely, Polymer Chain Reaction Method (PCR) and the Restriction Fragment Length Polymorphism (RFLP). The DNA samples are extracted through multiple ways and then compared to find out the biological truth behind a father-child relationship. Utilizing these processes in a proper manner makes sure that the DNA relationship testing results obtained is accurate enough.
The individuals may do this DNA paternity testing themselves for self-satisfaction. In order to do this, homely kit is provided to the users with all the utility devices. Whereas, when the test is done for legal matters, it is essential to be conducted under the supervision of an expert legal professional. Thus, if you have a doubt, whether a particular person is your biological relative, using the DNA relationship testing would be of great help.
