Recent genetic studies, based on Y chromosome polymorphic markers, showed that Ashkenazi Jews are more closely related to other Jewish and Middle Eastern groups than to their host populations in Europe. However, Ashkenazim have an elevated frequency of R-M17, the dominant Y chromosome haplogroup in Eastern Europeans, suggesting possible gene flow. In the present study of 495 Y chromosomes of Ashkenazim, 57 (11.5%) were found to belong to R-M17. Detailed analyses of haplotype structure…

Population Genetics of the Ashkenazim

Ashkenazi Jews appear as a relatively homogenous population which has retained its identity despite nearly 2000 years of isolation and is closely related to other Jewish communities tracing their common origin to the Middle East.

Phylogenetic applications of whole Y-chromosome sequences and the Near Eastern origin of Ashkenazi Levites

The analysis of 16 whole R1 sequences shows that a set of 19 unique nucleotide substitutions defines the Ashkenazi R1a lineage, indicative of a geographic source of the Levite founder lineage in the Near East and its likely presence among pre-Diaspora Hebrews.

The origin of Eastern European Jews revealed by autosomal, sex chromosomal and mtDNA polymorphisms

The close genetic resemblance to Italians accords with the historical presumption that Ashkenazi Jews started their migrations across Europe in Italy and with historical evidence that conversion to Judaism was common in ancient Rome.

Haplotype analysis of α-thalassemia chromosomes reveals heterogeneity and multiple founders in Ashkenazi Jews.

Analysis of genetic variation in Ashkenazi Jews by high density SNP genotyping

Any putative advantage in whole genome association mapping using the AJ population will be highly dependent on regional LD structure, andLD in the AJ versus was lower than expected by some measures and higher by others.

The genetic variation in the R1a clade among the Ashkenazi Levites’ Y chromosome

Approximately 300,000 men around the globe self-identify as Ashkenazi Levites, of whom two thirds were previously shown to descend from a single male. The paucity of whole Y-chromosome sequences…

The population genetics of the Jewish people

The population genetic architecture of Jews helps to explain the observed patterns of health and disease-relevant mutations and phenotypes which continue to be carefully studied and catalogued, and represent an important resource for human medical genetics research.

Phylogeographic analysis of paternal lineages in NE Portuguese Jewish communities.

The genetic composition of the Portuguese Jewish communities from Trás-os-Montes is examined, with a high-resolution Y-chromosome typing strategy, to clarify how these communities avoided the expected inbreeding caused by over four centuries of religious repression.

Geographical Structure of the Y‐chromosomal Genetic Landscape of the Levant: A coastal‐inland contrast

A coastal‐inland, east‐west pattern of diversity and frequency distribution in several haplogroups within the small region of the Levant is found, likely to have arisen mainly from differential migrations, with different lineages introduced from the east and west.

Multiple origins of Ashkenazi Levites: Y chromosome evidence for both Near Eastern and European ancestries.

Comparisons with other Jewish and non-Jewish groups suggest that a founding event, probably involving one or very few European men occurring at a time close to the initial formation and settlement of the Ashkenazi community, is the most likely explanation for the presence of this distinctive haplogroup found today in >50% ofAshkenazi Levites.

Jewish and Middle Eastern non-Jewish populations share a common pool of Y-chromosome biallelic haplotypes.

The hypothesis that the paternal gene pools of Jewish communities from Europe, North Africa, and the Middle East descended from a common Middle Eastern ancestral population is supported, and most Jewish communities have remained relatively isolated from neighboring non-Jewish communities during and after the Diaspora is suggested.

The common, Near‐Eastern origin of Ashkenazi and Sephardi Jews supported by Y‐chromosome similarity

A preliminary evaluation suggests that the contribution of foreign males to the Ashkenazi gene pool has been very low (1% or less per generation).

The Y chromosome pool of Jews as part of the genetic landscape of the Middle East.

The investigation of the genetic relationship among three Jewish communities revealed that Kurdish and Sephardic Jews were indistinguishable from one another, whereas both differed slightly, yet significantly, from Ashkenazi Jews.

Armenian Y chromosome haplotypes reveal strong regional structure within a single ethno-national group

The haplotype distribution and pattern of genetic distances suggest a high degree of genetic isolation in the mountainous southern and eastern regions, while in the northern, central and western regions there has been greater admixture with populations from neighbouring Middle Eastern countries.

Two particularly striking features were seen: an extremely high level of Y-chromosomal differentiation between geographically close populations, accompanied by low diversity within some populations, and the occurrence of several recent bottlenecks or founder events.

Dual origins of Finns revealed by Y chromosome haplotype variation.

Genetic evidence for the dual origins of Finns is presented by evaluating the pattern of Y chromosome variation in 280 unrelated males from nine Finnish provinces and revealing two major star-shaped clusters of Y haplotypes, indicative of a population expansion from two common Y chromosomes.

Whereas the mtDNA results show that Caucasian groups are more closely related genetically to European than to Near Eastern groups, by contrast the Y-chromosome shows a closer genetic relationship with the Near East than with Europe.
