We are people born to be unique. Although the twins similar characteristics and gender are difficult to differentiate, there is still a big difference if you have enough to look into all layers of organs. The answer lies in the genetic markers in our DNA.
In this case we can even reconstruct the genetic profile of a person away from your family tree or family member is missing, that is the genetic inheritance happens in the family such as grandparents, parents and so on.
This identification method is now used for situations that have to be exhausted by the decomposition and the loss of medical records, all other available authentication methods.
For example, the 2001 World Trade Center, Hurricane Katrina and the 2005 tsunami in Southeast Asia from chaos 2004, requiring thousands of deaths a few days or weeks to get out to recover the bodies and to be brought into the morgue, as weather could improve, lack of volunteers Humanitarian seriously affected location and the lack of technology the situation.
Legal protocols and post-mortem was to examine features such as dental, fingerprint, sex, hair color, and others. In addition to the implementation of the other, as appropriate DNA, it is necessary for the identification of children missing some ante-mortem dental or fingerprint data.
With standardized procedures for the months it could properly match the body with the help of genetic markers. Furthermore, only about 50-60% of the 3025 people who died in the chaos of 9-11 were run to identify within 18 months.
Some DNA markers, which shows to be shared between the genetic profile of a deceased person and the profiles of several survivors “of the reference sample that a parent is found and can now be identified. Of course, the high cost of DNA testing and the lack of morgue lead slowly with expertise in these areas to destructive identification.
In 2006, the DNA Shoah Project aims to reach to give the burnt sacrifice left the respect they deserve past and create a database of DNA that can both serve as a genetic tree and a memorial to those who died.
The hope was to match the remains of the collected DNA samples from Holocaust survivors and descendants of the deceased.
