Alleged killer confesses after seeing police sketch
Assuming that the genetic material is deposited during the commission of a crime, then this is a great tool for identifying a suspect. The key issue is determining that the genetic material did not arrive at the crime scene at some other time.

Five Genes Help Form a Face
This work has been going on for quite some time. This article was published in 2012. Additionally, there are obvious effects of environmental influences, such as nutritional intake, which alter the general appearance of the face.
Five genes emerged as important to facial features, Kayser and his colleagues report today in PLoS Genetics. The genes influenced traits such as the width of the face, the distance between the eyes, and how far the nose sticks out.

However, it's not quite as simple as that...
On the downside, the work confirms what many had suspected. There are no common variants with large effects. It is likely that there are many hundreds or thousands of these variants each having a small influence on the face.

Genetics: It's Written On Your Face
If you can predict from genetics to physical features, then is the reverse also possible? And, if so, how accurate would that be?

Your Face Is Made Of Junk DNA!
Will this technology be used to create more attractive offspring? And, if so, what would be wrong with that?
