The Genetic Landscape of the US
Patterns of Genetic Ancestry of Self-Reported African Americans
Genome-wide ancestry estimates of African Americans show average proportions of 73.2% African, 24.0% European, and 0.8% Native American ancestry (
Table 1). We find systematic differences across states in the US in mean ancestry proportions of self-reported African Americans (
Figure 1 and
Table S2). On average, the highest levels of African ancestry are found in African Americans living in or born in the South, especially South Carolina and Georgia (
Figure 1Aand
Table S3). We find lower proportions of African ancestry in the Northeast, the Midwest, the Pacific Northwest, and California. The amount of Native American ancestry estimated for African Americans also varies across states in the US. More than 5% of African Americans are estimated to carry at least 2% Native American ancestry genome-wide (
Figures S1 and
and1D).1D). African Americans in the West and Southwest on average carry higher levels of Native American ancestry, a trend that is largely driven by individuals with less than 2% Native American ancestry (
Figure 1B). With a lower threshold of 1% Native American ancestry, we estimate that about 22% of African Americans carry some Native American ancestry
Over the past 500 years, North America has been the site of ongoing mixing of Native Americans, European settlers, and Africans (brought largely by the trans-Atlantic slave trade), shaping the early history of what became the United States. We ...

I didn't realize the coli was so full of c00ns completely ashamed of their very genetic hiistory.
Half the posts for the last three pages read like Uncle Ruckus scripts. "Yuh see Robert, my ancestors was created right here in these United States. In fact my family was a unique mixture of Aboriginal American people and the peaceful white settlers. I don't need to mythologize my ancestral history to feel good about myself Robert! Not a drop of pure nikka in me! History is murky, but I ain't got nothing to do with them big lip, nappy head African! They was created here in the United States!"
No-one is ashamed of, or has alluded to, being ashamed of our genetics. We are just acknowledging that we are our own ethnic group and people like you have a problem with that.
