Jewish group of branches: J1-Z18297


The Jewish branches can be grouped according to their Y-DNA characteristics. These characteristics are often related to a period between 10000ybp-4000ybp. Some branches had a founding father effect in that period outside the Middle East which gives information on the location of their ancestor at the time of the founding father. For other branches it is more likely that the ancestors were in the Middle East, where, in most cases, no founding father effect took place and population growth was continuous. An overview of the Jewish groups of branches is present.


This branch probably originates from the Levant.

It has several Jewish branches below it. The branches below it that are not Jewish could have had Jewish ancestors.

In the SNP-tree of Haplogroup J Z18297 has several branches. The two main branches are named Z18292 and ZS4307. The Z18297 ancestor is older than the start of Judaism.

The branch Z18292 has four branches that are known Jewish, and it is likely that the ancestor Z18292 lived in the region of the Levant. Not all branches are Jewish. An old branch has a single line to Britain (162205), a little more recent branch, but still 3000ybp has a line to Persia (378452). The Persian line is parallel to the M4320 branch, that has a clear Iberian-Ashkenazi line, including Sephardic and converso descendants. The M4320 branch has two descending lines: J1-Z18297-M4320a and J1-Z18297-M4320b. The first is a classic Ashkenazi line and the second is probably a person from Aleppo that migrated to Ukraine late and has only one measured descendant.

In the other branches of Z18292 have people from Iberia, Tunisia, Lebanon, Turkey, Italy

The other branch ZS4307 has one Ashkenazi subbranch and two subbranches that were detected in the Sardinia project of Paolo Francalacci. This branch has both ZS4292 and 1733 below it, but we don't yet know the tmrca. If we only look at ZS4307 the shared ancestor of the three (2x PF, 1x Ashkenazi) makes both possibilities acceptable: the ancestor lived in Sardinia and one of the descendants became Jewish in Italy (1), or the ancestor lived in the Levant and two descendants left early and went westward in the Mediterranean (2). In the context of the branch Z18292 the second scenario is slightly more likely.

In the Z18297 branch we have a few uncertain branches from Saudi Araboa-Kuwait-U.A.E. and one certain Z18297 branch from Saudi Arabia. Whether that is in the Z18292 or ZS4307 or none of the two is not yet known.
