Y-chromosome and mitochondrial DNA studies on the population structure of the Christmas Island community

Y-chromosome and mitochondrial DNA studies on the population structure of the Christmas Island community

Christmas Island is a remote Australian territory located close to the main Indonesian island of Java. Y-chromosome and mitochondrial DNA (mtDNA) markers were used to investigate the genetic structure of the population, which comprises communities of mixed ethnic origin. Analysis of 12 Y-chromosome biallelic polymorphisms revealed a high level of ... Read More
Y-chromosome and mtDNA polymorphisms in Iraq, a crossroad of the early human dispersal and of post-Neolithic migrations

Y-chromosome and mtDNA polymorphisms in Iraq, a crossroad of the early human dispersal and of post-Neolithic migrations

Analyses of mtDNA and Y-chromosome variation were performed in a sample of Iraqis, a scarcely investigated population of the “Fertile Crescent.” A total of 216 mtDNAs were screened for the diagnostic RFLP markers of the main Eurasian and African haplogroups. A subset of these samples, whose HVS-I sequences were previously ... Read More
Y-Chromosome distribution within the geo-linguistic landscape of northwestern Russia

Y-Chromosome distribution within the geo-linguistic landscape of northwestern Russia

Populations of northeastern Europe and the Uralic mountain range are found in close geographic proximity, but they have been subject to different demographic histories. The current study attempts to better understand the genetic paternal relationships of ethnic groups residing in these regions. We have performed high-resolution haplotyping of 236 Y-chromosomes ...

Y-chromosome distributions among populations in Northwest China identify significant contribution from Central Asian pastoralists and lesser influence of western Eurasians

Y-chromosome distributions among populations in Northwest China identify significant contribution from Central Asian pastoralists and lesser influence of western Eurasians

Northwest China is closely adjacent to Central Asia, an intermediate region of the Eurasian continent. Moreover, the Silk Road through the northwest of China once had a vital role in the east–west intercommunications. Nevertheless, little has been known about the genetic makeup of populations in this region. We collected 503 ... Read More
Y-chromosome diversity characterizes the Gulf of Oman

Y-chromosome diversity characterizes the Gulf of Oman

Arabia has served as a strategic crossroads for human disseminations, providing a natural connection between the distant populations of China and India in the east to the western civilizations along the Mediterranean. To explore this region’s critical role in the migratory episodes leaving Africa to Eurasia and back, high-resolution Y-chromosome ... Read More
Y-chromosome diversity in Sweden – A long-time perspective

Y-chromosome diversity in Sweden – A long-time perspective

Sixteen Y-chromosomal binary markers and nine Y-chromosome short tandem repeats were analyzed in a total of 383 unrelated males from seven different Swedish regions, one Finnish region and a Swedish Saami population in order to address questions about the origin and genetic structure of the present day population in Sweden ...

Y-chromosome diversity is inversely associated with language affiliation in paired Austronesian- and Papuan-speaking communities from Solomon Islands

Y-chromosome diversity is inversely associated with language affiliation in paired Austronesian- and Papuan-speaking communities from Solomon Islands

The Solomon Islands lie in the center of Island Melanesia, bordered to the north by the Bismarck Archipelago and to the south by Vanuatu. The nation’s half-million inhabitants speak around 70 languages from two unrelated language groups: Austronesian, a language family widespread in the Pacific and closely related to languages ...

Y-Chromosome evidence for a northward migration of modern humans into Eastern Asia during the last Ice Age

Y-Chromosome evidence for a northward migration of modern humans into Eastern Asia during the last Ice Age

The timing and nature of the arrival and the subsequent expansion of modern humans into eastern Asia remains controversial. Using Y-chromosome biallelic markers, we investigated the ancient human-migration patterns in eastern Asia. Our data indicate that southern populations in eastern Asia are much more polymorphic than northern populations, which have ... Read More
Y-Chromosome Evidence for Differing Ancient Demographic Histories in the Americas

Y-Chromosome Evidence for Differing Ancient Demographic Histories in the Americas

To scrutinize the male ancestry of extant Native American populations, we examined eight biallelic and six microsatellite polymorphisms from the nonrecombining portion of the Y chromosome, in 438 individuals from 24 Native American populations (1 Na Dené and 23 South Amerinds) and in 404 Mongolians. One of the biallelic markers ... Read More
Y-chromosome evidence suggests a common paternal heritage of Austro-Asiatic populations

Y-chromosome evidence suggests a common paternal heritage of Austro-Asiatic populations

The Austro-Asiatic linguistic family, which is considered to be the oldest of all the families in India, has a substantial presence in Southeast Asia. However, the possibility of any genetic link among the linguistic sub-families of the Indian Austro-Asiatics on the one hand and between the Indian and the Southeast ... Read More
