DNA testing is the most reliable way to confirm the biological relationship between two individuals. The most widely used test is the DNA paternity test, in which an alleged father is tested to determine if he is the biological father of a child or not. The test is relatively easy to do and is rubbing oral swabs in the mouth and presents them in laboratory tests.
However, there are situations in which the allegedParent is not available for testing, because it is dead. Many believe that in this case there is no solution for this problem and paternity can not be conclusively determined.
In fact, a number of ways to confirm the identity of the father. First, through links with DNA testing, a DNA paternity test is similar, but involves testing close relatives, which confirmedvarious types of relationships. Tests can be performed between brothers, uncles and cousins and grandparents. These tests are not within the scope of this article, but worth a visit as an option if the parents are not available for testing.
In case of death, we consider three different scenarios and what the client should do in these situations:
Case 1: If the person who has just died and it is still possible to obtain biological material from the body (usually), This period no longer than a week after the date of death, it is recommended that the client tries to obtain (if possible) samples of hair and nail root cuttings. A qualified laboratory should be able to extract DNA samples from these and the use of DNA for comparison of paternity.
Case 2: If the body has already been buried, for the samples can be obtained indirectly – for example with a toothbrush, comb (perhapscontain useful hairs), dentures or recently smoked cigarettes. These samples are likely DNA material, which can be used for the tests included. Success in obtaining these DNA samples to a number of factors, primarily the state of the sample and the amount of DNA it contains (eg smoking, compared to a relatively unused.)
Case 3: When the body was buried by a number of years, and samples availableare the skeletal remains, it is recommended that a bone fragment of the shaft of the femur and / og humerus weighing approximately 2 to receive and / or two teeth per person.
These are some of the options available. The most important is the ability to obtain a sample of the deceased, which may contain DNA. Of course, expects the cost and difficulty of obtaining a sample in Case 3 (eg exhumation of the body) are relatively higher than the mere acquisitionsome hair and nails of the body. However, each has its own peculiarities, and you should always seek the advice of an expert in this field (eg forensic pathologist) or the company that used to run the test.
