This type of testing is often associated with DNA paternity testing. This process determines if a male individual is the father of a child and is often used where the paternity of the child is questioned or must be established for legal reasons.
But the advent of cheap paternity test has also prompted people to have DNA testing done for other reasons. The DNA test can also give people information about their ancestors. The information revealed by the genetic tests can indicate where the persons ancestors were from and would indicate some details of their appearance such as eye and hair color.
Another use of DNA genetic testing is to establish some of the appearances of discovered human remains. These tests are often used in conjunction with skeletal remains from the Middle Ages or earlier periods. If viable DNA can be recovered from the skeleton, the testing can determine some details of the appearance of the living person. Combining the facial structure with the details of eye and hair color provided by the DNA testing allow artists to reconstruct the appearance of the individual even if they have been dead for centuries.
Another use of the DNA testing attempts to unravel some more recent mysteries. DNA testing can be used to confirm a familial relationship between two tested individuals. For example, the test can confirm that a discovered skeleton is the ancestor of a currently living individual or another discovered body.
Some situations present another difficulty. What if there is no second person or body to compare to the questioned skeleton. DNA testing can be used to determine the traits of hair and eye color of the skeleton. This can then be compared to known description of the individual and used to establish identity. This is useful in attempting to identify remains of individuals killed in recent wars.
The world of DNA has changed drastically even in the few decades since the science began. Not only is the testing more advanced and more affordable, but man’s understanding of the information has improved. This has included mapping of the common DNA genetic information found in many parts of the world. This allows the tested individual to not only learn about the physical traits of their ancestors but the part of the world they lived during early human history.
