מחקר: הגנים של כוהנים דומים לירדנים בדואים, תימנים וערבים.
יצב גבולות עמים תחת שבטי ישראל.... כנראה הכהנים דומים באופי שלהם ל-לירדנים בדואים, תימנים וערבים.
הגן הנו J-P58* chromosomes

Abstract It has been known for over a decade that a
majority of men who self report as members of the Jewish
priesthood (Cohanim) carry a characteristic Y chromosome
haplotype termed the Cohen Modal Haplotype (CMH). The
CMH has since been used to trace putative Jewish ancestral
origins of various populations. However, the limited
number of binary and STR Y chromosome markers used
previously did not provide the phylogenetic resolution
needed to infer the number of independent paternal lineages
that are encompassed within the Cohanim or their coalescence
times. Accordingly, we have genotyped 75 binary
markers and 12 Y-STRs in a sample of 215 Cohanim from
diverse Jewish communities, 1,575 Jewish men from across
the range of the Jewish Diaspora, and 2,099 non-Jewish
men from the Near East, Europe, Central Asia, and India.
While Cohanim from diverse backgrounds carry a total of
21 Y chromosome haplogroups, 5 haplogroups account for
79.5% of Cohanim Y chromosomes. The most frequent
Cohanim lineage (46.1%) is marked by the recently
reported P58 T->C mutation, which is prevalent in the Near
East. Based on genotypes at 12 Y-STRs, we identify an
extended CMH on the J-P58* background that predominates
in both Ashkenazi and non-Ashkenazi Cohanim and
is remarkably absent in non-Jews. The estimated divergence
time of this lineage based on 17 STRs is
3,190 § 1,090 years. Notably, the second most frequent
Cohanim lineage (J-M410*, 14.4%) contains an extended
modal haplotype that is also limited to Ashkenazi and non-
Ashkenazi Cohanim and is estimated to be 4.2 § 1.3 ky
old. These results support the hypothesis of a common origin
of the CMH in the Near East well before the dispersion
of the Jewish people into separate communities, and indicate
that the majority of contemporary Jewish priests
descend from a limited number of paternal lineages
