Evaluating self-declared ancestry of U.S. Americans with autosomal, Y-chromosomal and mitochondrial DNA
Open accessAbstract
The current U.S. population represents an amalgam of individuals originating mainly from four continental regions (Africa, Europe, Asia and America). To study the genetic ancestry and compare with self-declared ancestry we have analyzed paternally, maternally and bi-parentally inherited DNA markers sensitive for indicating continental genetic ancestry in all four major U.S. American groups. We found that self-declared U.S. Hispanics and U.S. African Americans tend to show variable degrees of continental genetic admixture among the three genetic systems, with evidence for a marked sex-biased admixture history. Moreover, for these two groups we observed significant regional variation across the country in genetic admixture. In contrast, self-declared U.S. European and U.S. Asian Americans were genetically more homogeneous at the continental ancestry level. Two autosomal ancestry-sensitive markers located in skin pigmentation candidate genes showed significant differences in self-declared U.S. African Americans or U.S. European Americans, relative to their assumed parental populations from Africa or Europe. This provides genetic support for the importance of skin color in the complex process of ancestry identification.

European Americans also have non-European ancestry, including African, Native American, and Asian, though it has been poorly quantified with some discordance among estimates even within studies.
“Studies have shown that European Americans also have non-European ancestry, including African, Native American, and Asian, though it has been poorly quantified with some discordance among estimates even within studies.29–32”
From The genetic ancestry of African Americans, Latinos, and European Americans across the United States (2015) · cites this paper as [31]
The Results (Autosomal DNA; page unavailable) report that self-declared U.S. Europeans averaged 93.2% European ancestry, with small components of other continental ancestries. But the Results (NRY-DNA and mtDNA; page unavailable) say their ancestry estimates were similar across genetic systems, and the Discussion describes relatively low admixture. The paper does not support the claim of discordant estimates within its study for this group. (LLM, conf=0.88)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
