The Balkan Peninsula is a complex cultural mosaic comprising populations speaking languages from several branches of the Indo-European family and Altaic, as well as culturally-defined minorities such as the Aromuns who speak a Romance language. [] Key Method We have paid special attention to the Aromuns, and sought to test genetically various hypotheses on their origins. MtDNA and Y-chromosome haplogroup frequencies in the Balkans were found to be similar to those elsewhere in Europe. MtDNA sequences and Y…

The key role of patrilineal inheritance in shaping the genetic variation of Dagestan highlanders

Geography and stochastic factors, such as founder effect and long-term genetic drift, driven by the rigid structuring of societies in groups of patrilineal descent, most likely acted as mutually reinforcing key factors in determining the high degree of Y-genetic divergence among these ethnic groups.

Reconstructing the Indian Origin and Dispersal of the European Roma: A Maternal Genetic Perspective

The results show that the maternal lineage composition in the Roma groups follows a pattern of different migration routes, with several founder effects, and low effective population sizes along their dispersal.

Genetic origin, admixture, and asymmetry in maternal and paternal human lineages in Cuba

The extensive process of population admixture in Cuba has left no trace of the paternal Native American lineages, mirroring the strong sexual bias in the admixture processes taking place during colonial times.

Linking Italy and the Balkans. A Y-chromosome perspective from the Arbereshe of Calabria

The hypothesis that the surname-chosen Arbereshe are representative of the Y-chromosome genetic variability of the Albanian founder population can contribute to the interpretation of the recent biological history of the southern Balkans is supported.

Are ethnic minorities synonymous for genetic isolates? Comparing Walser and Romance populations in the Upper Lys Valley (Western Alps).

The findings strongly suggest that the Walser communities' ethnic minority status is not associated with genetic isolation, whereas genetic isolation was found in the linguistically non-isolated Gaby.

Genetic Evidence for Complexity in Ethnic Differentiation and History in East Africa

The Nyangatom and Daasanach were found to be significantly differentiated, while each of them displays close affinities with some Tanzanian populations, suggesting processes, associated with periods of isolation, could explain the high diversity and strong genetic structure found in East Africa.

Mitochondrial DNA and Y-chromosomal stratification in Iran: relationship between Iran and the Arabian Peninsula

High-resolution mitochondrial DNA markers are utilizing and reanalyzing previously published Y-chromosomal data are reanalyzed to find a previously unexplored, genetic connection between Iranian populations and the Arabian Peninsula, likely the result of both ancient and recent gene flow.

Maternal Genetic Heritage of Southeastern Europe Reveals a New Croatian Isolate and a Novel, Local Sub‐Branching in the X2 Haplogroup

The results of 1035 samples show that the SEE maternal genetic diversity fits within a broader European maternal genetic landscape and shows that the population of Žumberak, located in the continental part of Croatia, developed some unique mtDNA haplotypes and elevated haplogroup frequencies due to distinctive demographic history and can be considered a moderate genetic isolate.

Linguistic, geographic and genetic isolation: a collaborative study of Italian populations.

The human genetic diversity of Italy was found to be greater than observed throughout the continent at short and intermediate distances, and accounted for most of the highest values of genetic distances observed at all geographic ranges.



Alu insertion polymorphisms in the Balkans and the origins of the Aromuns

The present results suggest a common ancestry of all Balkan populations, including Aromuns, with a lack of correlation between genetic differentiation and language or ethnicity, stressing that no major migration barriers have existed in the making of the complex Balkan human puzzle.

Mitochondrial DNA variation and the origin of the Europeans

Estimated expansion times indicate a Paleolithic event with important differences among populations according to their geographical position and thus a slower tempo than previously believed and the replacement of Neanderthals by anatomically modern humans may have been a slower and more complex process than cultural change suggests.

Y chromosomal evidence for the origins of oceanic-speaking peoples.

Diversity within the nonrecombining portion of the Y chromosome, which contains within it a relatively simple record of the human past and represents the most informative haplotypic system in the human genome, is assayed.

Isonymy, consanguinity and repeated pairs of surnames in Aromun populations.

The Aromuns represent a small and almost unknown people that live scattered over the Balkan Peninsula. Due to their language, that is very similar to classical Latin, they are in a special position.

The Eurasian Heartland: A continental perspective on Y-chromosome diversity

This study reports the frequencies of 23 Y-chromosome biallelic polymorphism haplotypes in 1,935 men from 49 Eurasian populations, with a particular focus on Central Asia.

Y-chromosomal diversity in Europe is clinal and influenced primarily by geography, rather than by language.

These patterns retain a strong signal of expansion from the Near East but also suggest that the demographic history of Europe has been complex and influenced by other major population movements, as well as by linguistic and geographic heterogeneities and the effects of drift.

The genetic legacy of Paleolithic Homo sapiens sapiens in extant Europeans: a Y chromosome perspective.

A significant correlation between the NRY haplotype data and principal components based on 95 protein markers was observed, indicating the effectiveness of NRY binary polymorphisms in the characterization of human population composition and history.

Mitochondrial DNA Variability in Bosnians and Slovenians

The observed differentiation between Bosnian and Slovenian mtDNAs suggests that at least two different migration waves of the Slavs may have reached the Balkans in the early Middle Ages.

Geographic patterns of mtDNA diversity in Europe.

The distribution of the zones of highest mitochondrial variation (genetic boundaries) confirmed that the Saami are sharply differentiated from an otherwise rather homogeneous set of European samples, and an area of significant clinal variation was identified around the Mediterranean Sea (and not in the north), even though the differences between northern and southern populations were insignificant.
