Millie and mar shall BIGS. Julia Mcfarland has their story. Reporter: Meet Marcia and Millie Biggs. Their dad is black. Their mom is white. She calls them her one in a million miracle. Blessed to have two beautiful daughters. Oh, thanks. I'll pay yaw later. Reporter: Marcia has pale skin. Millie has darker complexion. People can't tell you. They can't say you're white or black. You're kind of both. Reporter: Now, they're on the sprilover of "National geographic's" issue on race. Wow. Reporter: They are often mistaken for friends. Not defined by the the color of their skin. I think race schism a negative thing. Racism is where somebody jums you by your color. Not by your actual self. Reporter: For Marcia and Millie, it bypasses what means the most to them. They're friends who love to be together. It's best to celebrate the skin you're in. It's better to be different from other people. You can just be yourself. Reporter: For "Good morning America," Julie Mcfarland, ABC news, Birmingham. A terrific message.
