Heather Dewey-Hagborg is a talented information artist behind this awesome project “stranger visions” which created a series of portraits from the DNA collected from some biomaterials found on streets like chewing gums, cigarette heads, drinking cups and fallen hair of the people.

Your DNA is a blueprint to build you. All you need to look for is known segments of DNA that code for certain things. Obviously it’s a lot more complicated than this and I highly doubt we’re at the point where we can ACTUALLY build someone’s face accurately just from looking at their genetics, but there’s no reason it shouldn’t be possible. If you know what segment codes for eye color AND all the possible variants (knowing only what segment codes for eye color doesn’t tell you WHAT color it’s coding for), then you should be able to identify the eye color of the person who that DNA belonged to. In theory, the same goes for lip thickness, nose prominence, cheek bones, etc.
But again, we’re really not at the point where we can accurately recreate someone’s face from their DNA. This is just art. We need much, MUCH more data to learn how most of our genes express themselves, as well as the effects of our environment on gene expression. Knowing someone’s genetics isn’t necessarily going to tell you if they have Fetal Alcohol Syndrome, which can massively impact someone’s facial shape.
