Commentary on POTA

every individual human being has about 6 billion bases of DNA, which are contained in his or her 46 Chromosomes. Out of these 6 billion only 3 million may be identified from individual to individual because they form unique sequences. The rest of the DNA sequences are common with the sequences of all living beings. This makes very difficult to differentiate and identify individuals with absolute certainty. Additionally the methods adopted to test and identify individuals have inherent flaws on the first hand and on the other not all the sequences in regions which are supposed to differentiate individuals are targeted, ‘probed’ and tested (at the most four or five regions are tested).
In this way the testing data obtained are random and not complete or absolute. Because of this reason the DNA fingerprinting results and the reports which come before the courts as evidence is in terms of probabilities. The opinion of DNA expert is in form of a numerical statement known as “match probabilities”.

The presented book is a questionnaire on the infallibility of DNA evidence to be conclusive proof of guilt, to shed-off the exotic myth, deliberately created as aureole around DNA evidence.
