Ossetians are a unique group in the Caucasus, in that they are the only ethnic group found on both the north and south slopes of the Caucasus, and moreover they speak an Indo‐European language in contrast to their Caucasian‐speaking neighbours. We analyzed mtDNA HV1 sequences, Y chromosome binary genetic markers, and Y chromosome short tandem repeat (Y‐STR) variability in three North Ossetian groups and compared these data to published data for two additional North Ossetian groups and for South… 
Parallel evolution of genes and languages in the Caucasus region.
TLDR
Overall, in the Caucasus region, unmatched levels of gene-language coevolution occurred within geographically isolated populations, probably due to its mountainous terrain.
Gene pool of ethnic groups of the Caucasus: Results of integrated study of the Y chromosome and mitochondrial DNA and genome-wide data
TLDR
It has been found that the West Asian component is prevailing in all ethnic groups studied except for Nogay, and Turkic-speaking populations, except Nogays, did not exhibit an increased proportion of Eastern Eurasian mtDNA or Y-chromosome haplogroups compared to some Abkhaz-Adyghe populations.
Landscape Complexity in the Caucasus Impedes Genetic Assimilation of Human Populations More Effectively than Language or Ethnicity
TLDR
The results suggest that landscape permeability was a stronger factor limiting gene flow among human populations in the Caucasus than were ethnic or linguistic boundaries.
Distinguishing the co-ancestries of haplogroup G Y-chromosomes in the populations of Europe and the Caucasus
TLDR
No clinal patterns were detected suggesting that the distributions are rather indicative of isolation by distance and demographic complexities, and the P303 SNP defines the most frequent and widespread G sub-haplogroup.
Genetic analysis of uniparental and autosomal markers in human populations
The main objectives of this thesis are to describe the distribution of genetic diversity in modern human populations and the distribution across subpopulations, with emphasis on the populations of
Ancient DNA reveals male diffusion through the Neolithic Mediterranean route
TLDR
The Y-haplotype lineages characterized and the study of their current repartition in European populations confirm a greater influence of the Mediterranean than the Central European route in the peopling of southern Europe during the Neolithic transition.
Migration and Interaction in a Contact Zone: mtDNA Variation among Bantu-Speakers in Southern Africa
TLDR
This study analyzes complete mtDNA genome sequences from over 900 Bantu-speaking individuals from Angola, Zambia, Namibia, and Botswana to investigate the demographic processes at play during the last stages of the BantU expansion.
Linking between genetic structure and geographical distance: Study of the maternal gene pool in the Ethiopian population
TLDR
It could be affirmed that, on a continent scale, the mtDNA pool of Africa, Europe and the Middle East might fall under the IBD model.
Genetic diversity of Besermyans inferred from mitochondrial DNA polymorphism
TLDR
The data obtained favor the suggestion on the mixed Udmurto-Turkic origin of Besermyans, the Finno-Ugric ethnic group related to Udmurts, due to the presence of a large proportion of the Mongoloid component in mtDNA diversity.

Mitochondrial DNA and Y‐Chromosome Variation in the Caucasus
TLDR
Overall, the Caucasus groups showed greater similarity with West Asian than with European groups for both genetic systems, although this similarity was much more pronounced for the Y chromosome than for mtDNA, suggesting that male‐mediated migrations from West Asia have influenced the genetic structure of Caucasus populations.
Mitochondrial DNA variation and language replacements in the Caucasus
TLDR
The mtDNA evidence suggests that the Armenian and Azerbaijanian languages represent instances of language replacement that had little impact on the mtDNA gene pool.
Mitochondrial DNA analysis reveals diverse histories of tribal populations from India
TLDR
Analysis of the first hypervariable region of the mitochondrial DNA (mtDNA) control region in 752 individuals from 17 tribal and four nontribal groups from the Indian subcontinent suggested that caste and tribal groups are genetically similar with respect to mtDNA variation.
Genetic diversity in the Iberian Peninsula determined from mitochondrial sequence analysis
TLDR
The timing of divergence of populations within Iberia points to a shared ancestry of all populations in the Upper Palaeolithic, and lineage diversity comparisons with European and North African populations shows the Iberian Peninsula to be more similar to other European populations, although a small number of Iberians lineages can be traced to North Africa.
Trading genes along the silk road: mtDNA sequences and the origin of central Asian populations.
TLDR
It seems unlikely that altitude has exerted a major selective pressure on mitochondrial genes in central Asian populations, because lowland and highland Kirghiz mtDNA sequences are very similar, and the analysis of molecular variance has revealed that the fraction of mitochondrial genetic variance due to altitude is not significantly different from zero.
Melanesian origin of Polynesian Y chromosomes
Paleolithic and neolithic lineages in the European mitochondrial gene pool.
TLDR
It follows that the major extant lineages throughout Europe predate the Neolithic expansion and that the spread of agriculture was a substantially indigenous development accompanied by only a relatively minor component of contemporary Middle Eastern agriculturalists.
Y chromosomal DNA variation and the peopling of Japan.
TLDR
Four loci mapping to the nonrecombining portion of the Y chromosome were genotyped in Japanese populations from Okinawa, the southernmost island of Japan; Shizuoka and Aomori on the main island of Honshu; and a small sample of Taiwanese, confirming the irregular distribution of this polymorphism in Asia.
[Gene pool of residents of northeastern Eurasia in light of data on polymorphism of mitochondrial DNA. I. New data on polymorphism of restriction sites of the D-loop of mtDNA in aboriginal populations of the Caucasus and Siberia].
TLDR
Only polymorphism in the Hae III site at the position 16,517 in the population of Eurasia was characterized with frequencies close to equilibrium that determined the extremely large evolutionary age of this polymorphism.
