I was watching the news yesterday and there is a young woman who is an artist. What she has done is walk the streets and pick up cigarette butts and other materials that may contain DNA. She then does an artist rendition of what the person may look like<quoted text>
You are correct at present. At this time in DNA technology, we cannot definitively determine race. However, DNA science has improved to the point where they can make an "educated guess" as to the race of the contributor.
In the future, we MIGHT be able to determine race, but there would still be another major problem with people who come from mixed races or ethnic. Most African Americans in the United States have some Caucasian ancestry in their backgrounds. This would complicate the matter greatly.
What CAN be determined using DNA would be gender, and blood type, and parenthood. This, of course, is if you have the profiles that show these things.
She has a lab, runs the DNA and while they can NOT determine race in any "specific" manner, they can make a fairly good determination of ancestry. They cannot determine age either so all of her "art" is made with a 20-30 years of age range. She uses a 3D imager and makes the faces.
You can watch this when you put the link together.
