I got a letter from this lady of Russian and Jewish descent. She asked me if I was a racist because I didn't do any White people. I was shocked, because my mandate is to do Black studies. It would have never occurred to me if this lady hadn't written this letter. We decided we were going expand the brand and do everybody.

The Dominican Republic says 'We're black behind the ears.' And in Mexico, 'there's a black grandma in the closet.' They know, they've just been intermarrying for a long time. But if we did the DNA of everyone in Mexico a whole lot of people would have a whole lot of black in them.

We really invented the genre of tracing family trees and going back as far as we could on the paper trail. When the paper trail disappeared, we used DNA analysis. The technology was just being invented that allowed you to trace ancestry through DNA.

My father and I made genetics history. We were the first African-Americans and the first father and son anywhere to have their genomes sequenced.

My father, if anything, first and last, was a man of words. He loved stories; he didn't live for stories, exactly, but I think he lived through stories. I think, like many writers, he loved stories about things he had experienced as much as, if not more than, he loved the experiences themselves.

Everything my mother and father did was designed to put me where I am.

I thought, "why don't we be innovative and create something nobody had ever done before?" It was a huge hit and we immediately did a sequel with Chris Rock, Morgan Freeman, Tina Turner and Maya Angelou.
