This gray 3D-printed face is my actual face.

But this white one is based solely on my DNA.

It's not an exact match, to say the least.

improving their ability to identify people

In criminal cases involving unidentified remains,

recognition can be the last chance to develop leads

giving a victim their identity back could close the case.

The image got 26-year-old Shaquana Caldwell recognized,

and, in turn, caught her killer after months with no leads.

Parabon combined two methods of facial reconstruction,

And that's thanks to single-nucleotide polymorphisms,

the variations in base pairs throughout our genes.

most associated with having brown or hazel eyes.

Mark and his team are building a database

that have significant effects on the face.

Abby: At the moment, their formula isn't perfect.

A lot of traits are controlled by multiple SNPs,

so it isn't a simple one-to-one connection.

And my nose is a bit pointier in reality.

I don't usually think I look like my dad,

Then those are probably genes with big effects,

because, you know, those differences that you see

Like you said, your face looks like your dad.
