6. common problems As with many other issues in the scientific world, aspects of DNA Fingerprinting is also not guaranteed 100%. The term DNA Fingerprinting (DNA fingerprinting) if the review only in the sense that the language is not precise. If using this term IE like the fingerprints of VNTR pattern must be unique to that individual's. In fact, everything that a VNTR model can give just the possibility of a true question is (a child, a trail of crime, ...) have provided VNTR model or not. 6.1 reliability Possibility of a DNA fingerprint belonging to a determined need special accuracy in the criminal case, the area where a small error can jeopardize the life of one man. The use of models or a combination rare in the VNTR many VNTR model to create a model of VNTR needed will increase the reliability of the two DNA samples match really (i.e. removed many cases two DNA samples it looks the same but actually they are not of one person) or closely related (in the case of determining the blood). 6.2 population genetics Because the VNTR is the result of genetic inheritance should not be cross-distribution across all populations. Fixed MộtVNTR so that there cannot be a stable appearance probability that it will change dependent on the genetic background of the individuals. The differences in the probability of occurrence of a given VNTR proved especially evident between the races. A couple of VNTR appeared regularly in the Spanish race very rarely appear in human or Non-human shift Cable. Today people still don't know enough about the frequency distribution of VNTR between peoples to assert precisely the separate definition of them. The genetic composition of a large number of heterogeneous individuals bred to create a whole new set of questions. Further experiments in the field of population genetics have been hampered very much due to the controversy, the pen war around comments about individual identification based on these genetic abnormalities. 6.3 technical difficulties The probability of errors in the process of hybrid molecules as well as catching the pair with the probe needs to be clarified. Of course, maybe the flaws are not accepted. All everyone that an innocent man could not be imprisoned, a criminal was not allowed heaths on the street or a mother must be right to raise his child. All things like that again depends on the technical staff. If he conducted experiments carefully, then everything will be good and vice versa. Assuming as when only one very small amounts of sample DNA, then the technician must make real careful, or like in human reaction experiments the gene if gen is compounded as the gene from the skin cells of people who fall into the experiment, the results would be completely wrong. So far the standards to affirm the coincidence of the DNA fingerprint, used in laboratories to reduce the errors, yet rigorous drafting and whole. Because of this so far DNA fingerprints are still more or less social protest.
