Abstract

Understanding the genetic structure of human populations is of fundamental interest to medical, forensic and anthropological sciences. Advances in high-throughput genotyping technology have markedly improved our understanding of global patterns of human genetic variation and suggest the potential to use large samples to uncover variation among closely spaced populations. Here we characterize genetic variation in a sample of 3,000 European individuals genotyped at over half a million variable DNA sites in the human genome. Despite low average levels of genetic differentiation among Europeans, we find a close correspondence between genetic and geographic distances; indeed, a geographical map of Europe arises naturally as an efficient two-dimensional summary of genetic variation in Europeans. The results emphasize that when mapping the genetic basis of a disease phenotype, spurious associations can arise if genetic structure is not properly accounted for. In addition, the results are relevant to the prospects of genetic ancestry testing; an individual's DNA can be used to infer their geographic origin with surprising accuracy-often to within a few hundred kilometres.

  • European Americans have a history of admixture of many genetically distinct European populations.

    “European Americans, however, have a history of admixture of many genetically distinct European populations.27,28”

    From The genetic ancestry of African Americans, Latinos, and European Americans across the United States (2015) · cites this paper as [27]

    The paper reports genetic structure among European populations (Abstract; page unavailable) and notes some individuals with mixed grandparental ancestry. It does not establish a history of admixture among European Americans; the Methods say individuals with putative origins outside Europe, including Europeans from the USA, were excluded. (LLM, conf=0.82)

  • Regions of the genome that have structural variation or show strong linkage disequilibrium (LD) have been shown both to confound admixture mapping and to influence the detection of population substructure in studies using Principal Components Analysis (PCA).

    “Regions of the genome that have structural variation or show strong linkage disequilibrium (LD) have been shown both to confound admixture mapping and to influence the detection of population substructure in studies using Principal Components Analysis (PCA).27,63,65”

    From The genetic ancestry of African Americans, Latinos, and European Americans across the United States (2015) · cites this paper as [27]

    The Methods section (Principal components analysis; page unavailable) says the authors filtered regions of strong linkage disequilibrium to avoid PCA artefacts and removed inversion regions, supporting the claim about detecting population substructure with PCA. Our copy does not say that these regions confound admixture mapping; it discusses genome-wide association studies instead. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • The use of four-grandparent birth-country has been utilized as a proxy for assessing ancestry.

    “The use of four-grandparent birth-country has been utilized as a proxy for assessing ancestry.27,63”
  • The block bootstrap gives better variance estimates than the jackknife for these pairwise allele frequency comparisons.

    “This gives better variance estimates than the jackknife for these pairwise allele frequency comparisons34.”

    From Paths and timings of the peopling of Polynesia inferred from genomic networks (2021) · cites this paper as [34]

    The Methods Summary describes leave-one-out cross-validation, and the Methods describe SNP filtering and association simulations. Neither those passages nor searches for “block bootstrap,” “jackknife,” and “variance estimates” address a comparison of the two methods for pairwise allele-frequency comparisons. (LLM, conf=0.75)

    Experimental — accuracy not yet measured
  • The alignment of the first two genetic PCs with geography and the clustering of individuals by European country are consistent with the results of a previous larger study of European genetic structure.

    “The alignment of the first two genetic PCs with geography and the clustering of individuals by European country are consistent with the results of a previous larger study of European genetic structure [28].”

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.
