Abstract

The current genetic makeup of Latin America has been shaped by a history of extensive admixture between Africans, Europeans and Native Americans, a process taking place within the context of extensive geographic and social stratification. We estimated individual ancestry proportions in a sample of 7,342 subjects ascertained in five countries (Brazil, Chile, Colombia, México and Perú). These individuals were also characterized for a range of physical appearance traits and for self-perception of ancestry. The geographic distribution of admixture proportions in this sample reveals extensive population structure, illustrating the continuing impact of demographic history on the genetic diversity of Latin America. Significant ancestry effects were detected for most phenotypes studied. However, ancestry generally explains only a modest proportion of total phenotypic variation. Genetically estimated and self-perceived ancestry correlate significantly, but certain physical attributes have a strong impact on self-perception and bias self-perception of ancestry relative to genetically estimated ancestry.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Kirkegaard et al. assessed genetic ancestry with 15,000 SNPs, making their index highly reliable.

    “They assessed genetic ancestry with 15,000 SNPs, making their index highly-reliable [56].”

    From Global Ancestry and Cognitive Ability (2019) · cites this paper as [56]

    The Results (Ancestry estimation) say this study estimated ancestry using 30 highly informative SNPs, not 15,000. The Materials and Methods (Genetic admixture estimation) report a correlation of approximately 0.7 with estimates based on 50,000 markers. Our copy does not establish how Kirkegaard et al. assessed ancestry. (LLM, conf=0.89)

    Checked by a reasoning model — may be wrong.

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.
