Even seemingly simple features such as height have proved difficult to predict. A recent paper from Kayser’s lab reported an analysis of nearly 10,000 Dutch volunteers, taking 180 SNPs into account. It found that it was possible to predict whether a person would be unusually tall with reasonable accuracy, but not nearly as well as eye color can be predicted. “This is a large number of SNPs explaining a not-so-large number of height variations,” he says.

Faces will be much more difficult, he adds, and creating a test that looks at all of the possible SNPs will be a technical challenge requiring samples of high-quality DNA in more than trace amounts — a luxury that forensic investigators rarely have.
