It’s worth noting that the vast, vast majority of Jewish Israelis are of Eastern European descent and also have no “genetic” claim to Israel. Ironically, most Biblical Israelites converted to Christianity and Islam centuries ago and are essentially lost to generic history as a group.
Actually, if I understand your comment correctly, you are incorrect. Genetic analysis can disprove your statement. Genebase in Canada is excellent and Nat Geo’s genetic group does a good job.
My brother had his DNA done after I sent my family the results of mine (now confirmed by three other genetic companies) that showed Ashkenazi line by mtDNA (H24a1). My brother, in an effort to show we were NOT Jewish at any level, had his DNA done and he came up as J1c3(p58+). Unfortunately my other brother is still in denial. I am very sorry I have missed knowing and understanding the rich religious and cultural history of the Jews.
So, you see, it doesn’t matter where you are or how long your family has denied bying Jewish, if you look and do the DNA testing, you can confirm or deny your Jewishness.
