[quote CayrolBaaaskin]@rosiejaune - it’s just rubbish what you’re saying. Ashkenazi jews are from a whole host of different backgrounds they are not 50 % middle eastern. Certainly many Jews are white but may have a different culture from other whites (same as black Jews or Chinese Jews).
You don’t speak for Jews any more than op speaks for all black people. We are each one person with our own experiences.[/quote]
Ashkenazi Jews all descend from a group of about 350 people, several hundred years ago, who had approximately 50% Middle Eastern DNA, 35% southern European DNA, and 15% eastern European DNA.
They then procreated and spread out all over Europe (and later beyond), but because they almost exclusively married within their own culture/ethnic group (it's called endogamy), their descendants had the same combination of ethnicities.
That explains why Ashkenazi Jews are more closely related to each other than they "should" be. E.g. you will appear to have loads of 3rd cousins if you take a DNA test and share the results online, because you are related to those people in multiple ways, but most of them are not actually your 3rd cousins. They could be e.g. your 5th cousin on one side, and your 6th cousin on the other side.
And it explains why Ashkenazi Jewish DNA is so easily identifiable on DNA tests; because we share a lot of genetic markers with each other.
So although Ashkenazi Jews come from many different European countries, they don't tend to have e.g. Polish DNA, or Romanian DNA, they have Ashkenazi Jewish DNA, because they didn't intermarry with the locals, on the whole.
