From Asia to Europe: mitochondrial DNA sequence variability in Bulgarians and Turks

Abstract

Summary: Two hypervariable sequence segments in the control region of mitochondrial DNA were determined in samples of Bulgarians and Turks. The Turkish sample presented a higher degree of internal diversity, in terms of total number of variable nucleotides, as well as in the average pairwise nucleotide difference. Pairwise difference distributions were built for both samples, yielding smooth bell shapes in agreement with the Rogers and Harpending model. The Bulgarian and Turkish data were compared with several European and W. Asian Caucasoid populations (Basques, Tuscans, Sardinians, British, Middle Easterners and Indians). Mean pairwise differences suggest that a demographic expansion occurred sequentially in the Middle East, through Turkey, to the rest of Europe (Bulgaria included). Current mutation rate estimates date this expansion in times ranging between 50000 and 100000 years ago and, thus, would correspond to the arrival of anatomically modern humans in Europe. Sequence trees for segment I show that European and Middle Eastern sequences derived from the reference sequence. Coalescence times for segment I sequences agree with those predicted by pairwise distributions. Genetic trees were constructed between populations and revealed an extreme homogeneity between European samples.

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

  • Low genetic differentiation was found between the 60 ancient mtDNA HVR1 sequences and 246 modern homologous sequences from the same geographic region (FST = 0.00551; P = 0.0663).

    “we compared the 60 mtDNA HVR1 sequences obtained from our ancient sample to 246 homologous modern sequences (29–31) from the same geographic region and found low genetic differentiation (FST = 0.00551; P = 0.0663) (32).”

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.
