Molecular anthropologists are often asked if DNA markers can tell what "race" you are. The short answer is "no." Mitochondrial DNA and Y haplogroups can tell from which continent your matrilineal and patrilineal ancestors came. And if you live in the Americas, autosomal mapping can tell what fraction of your ancestors came from Africa as slaves, what fraction came from Europe as colonists, and what fraction were Native Americans. But no DNA can tell your "race."
