You can also distinguish Chinese Catholics from Caucasian ones genetically, doesn't make a religion a genetic trait.
This casual form of anti-semitism displayed here, is somewhat bothering me.
Edit: Out of curiosity, since you seem very knowledgable, what's the exact gene sequence identified as being "Jewish" between those groups you mentioned? Honestly, I really thought actual genetics would be the end of that stupid eugenics crap, and not be used to sell the same shitty ideas in new disguise.
Yeah and I never said the religion was a genetic trait. There are ethnic Jews who don't practice the Jewish religion, and there are practicing Jews who aren't part of the "classical" Jewish ethnic groups (Ashkenazi, Sephardic, and so on). "Who is a Jew" is a big and complicated enough question that it has its own Wikipedia article. "Jewish" does not just mean religion. I don't see how knowing these basic things has anything to do with "antisemitism".
> what's the exact gene sequence identified as being "Jewish" between those groups you mentioned?
There's no exact gene that is dispositive. Human ethnic groups aren't genetically divergent enough for that. But there are alleles that are more or less common across groups.
You might have some SNP that's 70% prevalent in group A, and 40% prevalent in group B, and 10% prevalent in group C. That SNP alone isn't enough to tell you what group someone belongs to. But there are millions of SNPs, each of which has its own frequency distribution. There is structure within all that variation. When you aggregate that information you get a pretty strong signal, enough to reliably cluster the genotypes, and those clusters correspond with identifiable ethnic groups. You can estimate how much Jewish ancestry someone has, or indeed how much ancestry from any ethnic group that we have enough data for.
So, there is no "Jewish gene" (or "Chinese gene" or "Scottish gene"), but ethnic Jews are nevertheless genetically identifiable, from having higher or lower probabilities of having many different genetic variants. And this is not some academic matter, it is very important for human health. There are a few genetic disorders that, while not exclusively found in Jews, are unusually common among them. For example, Tay-Sachs disease:
For decades now, there have been Tay-Sachs genetic screening programmes among Jewish communities. This reduces the probability of two recessive carriers marrying one another. It has been very successful:
>Screening for Tay–Sachs carriers was one of the first great successes of the emerging field of genetic counseling and diagnosis. Proactive testing has been quite effective in eliminating Tay–Sachs occurrence among Ashkenazi Jews, both in Israel and in the diaspora.[13] In 2000, Michael Kaback reported that in the United States and Canada, the incidence of TSD in the Jewish population had declined by more than 90% since the advent of genetic screening.[14] On January 18, 2005, the Israeli English language daily Haaretz reported that as a "Jewish disease" Tay–Sachs had almost been eradicated. Of the 10 babies born with Tay–Sachs in North America in 2003, none had been born to Jewish families. In Israel, only one child was born with Tay–Sachs in 2003, and preliminary results from early 2005 indicated that none were born with the disease in 2004.[15]
Would you describe this as "stupid eugenics crap"?
