A new study finds many people who identify themselves as completely white also have African ancestry.

Researchers looked at a comprehensive database of genetic information collected by the gene identifying service 23and Me.

One of the biggest discoveries was that self-identified white people from the South have the highest concentration of African genes in the United States, with states like Louisiana and South Carolina showing one in 20 have at least 2 percent African ancestry.

The researchers also found people who identify as African-American have the highest concentration of African genes in the South, with self-identified black people in the North showing more mixed heritage.
