6. Common Issues Like many other issues in the world of science, aspects of DNA Fingerprinting is not guaranteed 100%. DNA Fingerprinting term (DNA fingerprints) if only in the sense that language is not accurate. If that is the term used like fingerprints VNTR patterns of an individual is the only instance of this. In fact everything that a VNTR patterns can make just as likely an individual is suspected individual right (a child, a trace of the crime ...) provided VNTR patterns or not. 6.1 Confidence Likelihood a DNA fingerprint belongs to a particular individual identified need high accuracy in the criminal case, the field where a small mistake can ruin the life of a the people. The use of rare models VNTR or VNTR patterns combine to create an essential VNTR patterns will increase the reliability of the conclusions of two DNA matching real (ie eliminate many schools DNA samples of two seemingly similar but actually they are not of a person) or an association (in the case of parents). 6.2 Genetics populations Because VNTR as a result of the genetic inheritance, are not distributed evenly across all human populations. Given VNTR therefore can not have a stable probability of occurrence but it will change depending on the genetic background of each individual. The difference in the probability of occurrence of a certain VNTR proved particularly evident among races. Some VNTR appear regularly in the Spanish race is very rarely seen in strains or isolates caucasian African American people. Today we still do not know enough about the frequency distribution of VNTR between peoples to affirm precisely their peculiarities. Heterogeneous genetic components of a large number of individual breed an entirely new questions. Further experiments in the field of population genetics has been hampered by a lot of controversy, polemics around ideas about individual identity based on genetic abnormalities. 6.3 technical difficulties Probability of errors in the process as well as hybrid molecules coupled to the probe needs to be clarified. Of course, errors can not be accepted. Everyone agreed that an innocent person can not be imprisoned, an unauthorized criminals roaming the streets or have a mother can raise her child. All such things depend on people technician. If he is conducting experiments carefully, things will go well and vice versa. Suppose that when only a very small amount of DNA sample, the technician must make very careful, or as in experiments with human genes react if the gene is duplicated genes from the skin cells of people doing experiments fall on the results will be completely wrong. So far the criteria for confirming the coincidence of DNA fingerprints, used in laboratories to reduce errors, yet to be drafted strict and whole. Because of this, DNA fingerprints hitherto more or less social protest.
