DNA is the basic biological blue print of a human being; it is a full representation of every attribute known from birth. This is usually inherited therefore both parents have a contribution and every cell in the body is stamped with this code. DNA therefore is a crucial index on matters of verification; be it in parentage or any conceived relationship. It can give any line up of any family tree and confirm the presence or absence of a relationship.

DNA paternity test therefore, is the investigation done in a science laboratory to determine whether two people have a biological relationship. The specific relationship is parent (father) to child connection. Paternity refers to the father; it is meant to establish whether a man in question is the true biological father of an individual. The test is rigorous; producing the most reliable results known at this age and time. In this test, the chances or probability is 0% if the man in question is not related to the subject; while the probability of paternity is 99.9% if there is a relationship. This kind of dead accuracy has been used to settle many court disputes and civil cases and thus the service is very remarkable.

DNA of every one of us is different; every cell of an individual has almost the same DNA print. In the gonads is where cell division occurs (meiosis) where the forty six chromosomes are halved to twenty three. Each sperm will carry the half while the ova from the female side will give the other half fusing to become one full individual of complete forty six. This understanding is crucial at all times and it opens up opportunities for people to come to amicable solutions. DNA is compared very well, its sequence is studied and for a son who is making some genuine claims, the genetic material will come out clearly as having been derived from his father. On the surface, all sons born will have a Y chromosome while daughters will have an X chromosome; and it is this follow up that leads to isolation so as to get source. This nuclear DNA is of paramount importance as opposed to mitochondrial DNA which mainly will give information of the mother of the subject.

DNA paternity test remains the basic proof of a relationship. At the moment this test has come to be regarded as crucial in matters of immigrations. The US government for example would rather go direct to the genes when birth information is lacking as a final determinant before issuing documents to individuals who are entering the US as relatives.

In many other circumstances, many mothers lay claims from individuals who sired their children; properties or pension deposits etc and when courts take over for arbitration, often paternity tests remain the only proof. This test also takes charge of matters pertaining to hospital mix ups, adoption of children, donated eggs and in many other critical areas that the demand proof beyond any reasonable doubt.
