The University of Pennsylvania created a program that draws portraits of DNA
A professor of anthropology and genetics at the University of Pennsylvania created a program that analyzes human DNA and paints his portrait. Scientists have figured out how genes affect facial creation. The program in a few minutes draws a portrait, connecting genetic markers and parts of the face. Why it is needed, scientists are still debating.
Mark Shriver, a professor of anthropology and genetics, with his team figured out how DNA affects the structure of a human face. The result of the study was a program capable of drawing a portrait. At first glance there is a similarity between the portrait and the original. Scientists find out in which areas the development can be applied.
To create the program, Dr. Shriver measured seven thousand points of a human face and analyzed their connections with thousands of genetic variants. The program makes a portrait based on a person’s field, information about his ancestors, and twenty-four variants in twenty genes responsible for the structure of the face.

The editors of the New York Times checked the compliance of the portraits to the originals. For this, the scientists sent the DNA of reporter John Markoff and videojournalist Katrin Spangler. In addition to DNA samples, there was no information - neither about weight, nor about height, nor about the age of the subjects. In the first photo - John Markoff, no one in the editorial office could recognize him from the portrait - right above. Later, Dr. Shriver introduced the age into the program, getting a portrait from the bottom right - more like the truth.
Catherine Spangler learned ten colleagues.
What are the uses for this technology? First of all, forensic science suggests itself. Modern developments allow us to find out the floor, eye color, hair color, possible country of the suspect. But it will be much more interesting if it is possible to simply print the identikit of a criminal on DNA, as it was done in the District of Columbia, USA. This portrait was made by another company - Parabon NanoLabs.
