In a study of Israeli Jews from some different groups (Ashkenazi Jews, Kurdish Jews, North African Sephardi Jews, and Iraqi Jews) and Palestinian Muslim Arabs, more than 70% of the Jewish men and 82% of the Arab men whose DNA was studied had inherited their Y chromosomes from the same paternal ancestors, who lived in the region within the last ...
Efforts to identify the origins of Ashkenazi Jews through DNA analysis began in the 1990s. There are three types of genetic origin testing, autosomal DNA (atDNA), mitochondrial DNA (mtDNA), and Y-chromosomal DNA . Autosomal DNA is a mixture from an individual's entire ancestry.
This set of advantages has led to Ashkenazi Jews in particular being used in many genetic studies, not just in the study of genetic diseases. For example, a series of publications on Ashkenazi centenarians established their longevity was strongly inherited and associated with lower rates of age-related diseases. [ 11 ]
This page is subject to the extended confirmed restriction related to the Arab-Israeli conflict. Khazar Khaganate, 650–850 The Khazar hypothesis of Ashkenazi ancestry, often called the Khazar myth by its critics, is a largely abandoned historical hypothesis that postulated that Ashkenazi Jews were primarily, or to a large extent, descended from Khazar converts to Judaism. The Khazars were a ...
It is hypothesized that the subclade represents one of four major founding maternal lineages ("founding mothers") of Ashkenazi Jews which together account for 45% of all Ashkenazi mtDNA haplotypes. Approximately 19% of Ashkenazi Jews with ancestry from Poland are in mtDNA haplogroup K1a1b1a. [ 2 ]
They found similar results analyzing DNA from Ashkenazi and Sephardi Jews. [51] The scientists estimated the date of the original priest based on genetic mutations, which indicated that the priest lived roughly 106 generations ago, between 2,650 and 3,180 years ago depending whether one counts a generation as 25 or 30 years.

Two possible G-M377 Y-STR haplotype samples in the literature are from the study of Jewish and non-Jewish Near Eastern Y chromosomes by Nebel et al. (2001) (in the Appendix Table A1), haplotype 51 which was found in 1 Ashkenazi Jew (n=79) and 3 Kurdish Jews [15] (n=99), and haplotype 47 which was found in 1 Iraqi Jew (combined Iraqi Jews n=20 ...
L2a1l2a is recognized as an "Ashkenazi-specific" haplogroup, seen amongst Ashkenazi Jews with ancestry in Central and Eastern Europe. It has also been detected in small numbers in ostensibly non-Jewish Polish populations, where it is presumed to have come from Ashkenazi admixture. [43]
