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

這張灰色的3D打印的臉是我真正的臉。

But this white one is based solely on my DNA.

但這個白色的是完全基於我的DNA。

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

至少可以說，這不是一個完全的匹配。

但是，法醫科學家們正在孜孜不倦地

improving their ability to identify people

In criminal cases involving unidentified remains,

在涉及身份不明的遺體的刑事案件中。

recognition can be the last chance to develop leads

認可可以是發展線索的最後機會

在傳統的方法不能發揮作用之後。

giving a victim their identity back could close the case.

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

該影像得到了26歲的沙誇納-考德威爾的認可。

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

反過來，在幾個月沒有任何線索的情況下，抓住了殺害她的凶手。

Parabon combined two methods of facial reconstruction,

帕拉邦結合了兩種面部重建的方法。

But this method won't ever be 100% accurate.

could get us as close as we can to a copy machine.

可以讓我們儘可能地接近複印機。

That's how we ended up at Shriver Lab at Penn State.

這就是我們如何在賓夕法尼亞州立大學的施萊弗實驗室結束的原因。

Sarita: This is just envelopes and envelopes of hair.

薩里塔。這只是一包一包的頭髮。

this cabinet full of hair would be really weird.

這個滿是頭髮的櫃子會非常奇怪。

Producer: Does everyone sound like this when they do it?

製片人。每個人做的時候都是這樣的聲音嗎？

Sarita: No! I've never heard anyone sound like this.

薩里塔。不！我從來沒有聽過有人像這樣的聲音。

I'm nervous I'm not going to recognize myself

我很緊張，因為我無法認出自己

not because it's not a good reproduction,

不是因為它不是一個好的複製品。

have a different vision of myself than reality.

馬克：準備好了嗎？艾比：我準備好了。

of my genetic info and the collected data

from people who share my genetic ancestry.

來自與我有相同遺傳血統的人。

meaning the predicted face is most recognizable,

意味著預測的臉是最容易被識別的。

我的實際面孔和預測的面孔之間。

我們在模型中需要更多的資訊。

艾比：人類共享大約99.9%的DNA。

And that's thanks to single-nucleotide polymorphisms,

而這要歸功於單核苷酸多態性。

the variations in base pairs throughout our genes.

我們整個基因中的鹼基對的變化。

這是最容易用我們的眼睛看到的。

most associated with having brown or hazel eyes.

與擁有棕色或淡褐色眼睛最相關。

Mark and his team are building a database

馬克：我們真的處於一個早期階段。

that have significant effects on the face.

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

艾比：目前，他們的配方並不完美。

A lot of traits are controlled by multiple SNPs,

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

所以它不是一個簡單的一對一的連接。

that we really rely on to identify each other

And my nose is a bit pointier in reality.

而我的鼻子在現實中是比較尖的。

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

我通常不認為我看起來像我父親。

Then those are probably genes with big effects,

那麼這些可能是有大影響的基因。

because, you know, those differences that you see

因為，你知道，你看到的那些差異

往往在他們的兄弟姐妹中脫穎而出。

Like you said, your face looks like your dad.

就像你說的，你的臉看起來像你爸爸。

Abby: Plus, SNPs are associated with different traits,

艾比：另外，SNP與不同的性狀有關。
