DNA contains all the information needed for the development of live organisms. Individuals from the same species share a big part of the DNA sequence, but there are certain regions highly variable that are specific of each subject. These areas of the genome are called polymorphisms or genetic markers and they are use for the identification of people, since it is very unlikely that two human beings not related to each other could share the same genetic markers. The group of polymorphisms specific of each person is known as genetic profile.
The individual genetic profile allows us to identify each person, except in the case of having a monozygotic twin brother, since in this case they share the same DNA sequence. The genetic profile characterizes each individual the same or even better than their own fingerprints, this is why it is called genetic trace. Its advantage is that is more precise than other identification methods. Also, DNA is found in each and every single cell of the human body, therefore it can be obtained from any biological sample. The genetic trace is invariable and unique along a person’s life.
The genetic trace is used in forensic medicine in the identification of human remains, paternity test or relationship, compatibility in organ donation... etc.
The situations when doing this kind of study could be very useful, among those, we list some below:
Finally, as an alternative service to obtaining the genetic trace of an individual, his own DNA could be kept for future usage:
The procedure is very easy. On the kit that you will receive, you will find sterile cotton buds, with which you would need to rub the internal side of the mouth of the subjects involve. Use the samples carefully. Use protection to touch the cotton buds. Once you have taken the samples and you have packed them properly under the directions given, you should send them to us with the corresponding forms.
If you would like the results to have legal validity, the samples have to be taken by professionals at one of our clinics, so the origin of the samples can be proven.
