Judy Siegel. "Genetic evidence links Jews to their ancient tribe." Jerusalem Post (November 20, 2001). Excerpts:
"Despite being separated for over 1,000 years, Sephardi Jews of North African origin are genetically indistinguishable from their brethren from Iraq, according to The Hebrew University of Jerusalem. They also proved that Sephardi Jews are very close genetically to the Jews of Kurdistan, and only slight differences exist between these two groups and Ashkenazi Jews from Europe. These conclusions are reached in an article published recently in the American Journal of Human Genetics and written by Prof. Ariella Oppenheim of the Hebrew University (HU) and Hadassah-University Hospital in Ein Kerem. Others involved are German doctoral student Almut Nebel, Dr. Marina Faerman of HU, Dr. Dvora Filon of Hadassah-University Hospital, and other colleagues from Germany and India. The researchers conducted blood tests of Ashkenazi, Sephardi and Kurdish Jews and examined their Y chromosomes, which are carried only by males. They then compared them with those of various Arab groups - Palestinians, Beduins, Jordanians, Syrians and Lebanese - as well as to non-Arab populations from Transcaucasia - Turks, Armenians and Moslem Kurds. The study is based on 526 Y chromosomes typed by the Israeli team and additional data on 1,321 individuals from 12 populations... Surprisingly, the study shows a closer genetic affinity by Jews to the non-Jewish, non-Arab populations in the northern part of the Middle East than to Arabs."
The studies are extensive and exhaustive, and the percentage of links vary from barely statistically significant, to a strong correlation. Of course, these are studies done by Jews... Arabs probably have their own studies showing the opposite.
Over 2000 years ago there were Jews and Gentiles, right..
When the Jews brought Jesus Christ A Jew to the Gentile World, did that cancel them out to be part of one of the tribes of Israel?
Gentiles cannot claim DNA to Jesus Christ only Jews can...
I have a vague memory of reading an Arab study of genetics, which claimed to show that Jews from Arab lands have some links to Jewish populations in the West, but these are slight, whereas they have more in common with Palestinians and other Arabs.
I don't know anything much about genetics, but I think you can tell, looking at people, what racial background they have. Jews from Arab lands look like Arabs.
