According the biblical accounts, the Jewish priesthood was established about 3,300 years ago with the appointment of the first Israelite high priest. Designation of Jewish males to the priesthood continues to this day, and is determined by strict patrilineal decent. Accordingly, we sought and found clear differences in the frequency of Y-chromosomes haplotypes between Jewish priests and their lay counterparts. Remarkably, the difference is observable in both Ashkenazi and Sephardic populations… Expand

Origins of Old Testament priests
TLDR
Although Levite Y chromosomes are diverse, Cohen chromosomes are homogeneous, and this work traces the origin of Cohen chromosomes to about 3,000 years before present, early during the Temple period. Expand
High Paternity Certainties of Jewish Priests
Recent evidence (Skorecki et al. 1997) of significant differences between the Y chromosomes of Jewish priests (Kohanim) and laymen (Israelites) indicate very high degrees of paternity certainty (p,Expand
Towards a Y-Chromosomal Materialization of the Biblical Abraham
Judaism, Christianity, and Islam refer to Abraham as the father of Isaac and Ismail who in turn are the founders of two genetic lines and religious traditions. Genetic research may materialize theExpand
The Geography of Jewish Ethnogenesis
A reevaluation of the anthropological genetics literature on Jewish populations reveals them not simply to be a body of genetically related people descending from a small group of common ancestors,Expand
Population Genetics of the Ashkenazim
TLDR
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. Expand
Genetic and phylogeographic evidence for Jewish Holocaust victims at the Sobibór death camp
TLDR
Archaeological excavations in the area of the death camp in Sobibór, Poland, revealed ten sets of human skeletal remains presumptively assigned to Polish victims of the totalitarian regimes, but genetic analyses indicate that the remains are of Ashkenazi Jews murdered as part of the mass extermination of European Jews by the Nazi regime.

Portuguese crypto-Jews: the genetic heritage of a complex history
TLDR
An unexpectedly high polymorphism of lineages was found in Bragança, showing a surprising resistance to the erosion of genetic diversity typical of small-sized isolate populations, as well as signs of admixture with the Portuguese host population. Expand

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.

Fathers and sons: the Y chromosome and human evolution.
TLDR
It is now possible to use selected, slowly evolve polymorphisms to draw a rudimentary Y chromosome tree, while more rapidly evolving polymorphisms allow most independent Y chromosomes to be distinguished. Expand
Analysis of molecular variance (AMOVA) of Y-chromosome-specific microsatellites in two closely related human populations.
TLDR
The analysis of seven Y-chromosome-specific microsatellite loci revealed a high level of polymorphism in two closely related human populations, allowing the characterization of the level of genetic distinctiveness of supposedly inbred or isolated populations and discrimination even between closely related populations.

A recent common ancestry for human Y chromosomes
TLDR
Inferences contradict predictions of the multiregional hypothesis positing a widespread transformation of Homo erectus populations into Homo sapiens and are consistent with auto-somal and mitochondrial DNA studies that suggest a long-term human effective population size of 10,000 and a sex ratio of 1.
