And according to research published by Kasia Bryc, research fellow at the Harvard Medical School, 96% of White Americans have less than 1% recent (meaning the last 2-300 years) African contribution to their DNA.
That means 4% of White Americans have a Black ancestor in the generations since the founding of the colonies in America.
Here is an interesting article and map concerning the subject.

Your info contradicts all published works.
Since we have some experts on the forum, I guess that they will abound on the subject.
I believe that I read a serious study that stated that the American Blacks that had less white blood were the ones living in some island off Georgia, and they had white blood. It seems that at the island, blacks there were descendants of "cimarrones", maroons in American, "palenqueros".
Published in the journal Genome Biology, the study does not offer much in the way of new information but its facts are still interesting.
For example, the study says the majority of American Blacks derive their ancestry from just 500,000 to 600,000 of the millions of Africans who were forcibly brought to North America as slaves during the Middle passage.
The African ancestry of American Blacks comes primarily from six tribal or ethnic groups:
Yoruba (63.7%), Mandenka (19.2%), Bantu (13.8%), San (2.0%), Blaka (1.0%) and Mbuti (0.2%).
Meanwhile, the genetic ancestry of the typical African American is 22 percent European with around 10 percent of U.S. Blacks being of more than 50 percent European ancestry. (source: Taylor Media Services)
