As a result of centuries of having children with white people, the majority of African Americans have some European admixture, and many white people also have African ancestry. Writer and editor Debra Dickerson questions the legitimacy of the one-drop rule, stating that "easily one-third of black people have white DNA". She argues that in ignoring their European ancestry, African Americans are denying their fully articulated multi-racial identities. The peculiarity of the one-drop rule may be illustrated by the case of singer Mariah Carey, who was publicly called "another white girl trying to sing black", but in an interview with Larry King, responded that—despite her physical appearance and the fact that she was raised primarily by her white mother—due to the one-drop rule, she did not "feel white". Recently, the possibility of genetic testing has raised new questions about the way African Americans describe their race.
