Explaining German Jewish admixture and genetic proportions is a lengthy lengthy explanation and study.
I only intend to post just 1 chart explaining Jewish Admixture proportions among a couple of Jewish identified individuals.
Ashkenazi Jews (AJS) are about half Middle Eastern (Quarter South West Asian (East Gulf Semitic?) + Quarter West Asian (Levantine, East Med, Near East Semitic)) and about half European (Southern European (Greeks, Italians, Southern Med.) + Northern European (Nords, Scandinavians, Vikings, Germans)).
Also please note that there doesn't seem to be a clear distinction between Near Easterners and South East Europeans due to the two groups being very similar genetically.
And to stay relevant to the Asian-ness.
We A. Jews also have outliers having tiny tiny blot blops of 1-2% Mongoloid East Asian and North East Asian DNA representing by the orange bars, due to Jews intermarrying with....... Mongoloid Silk Road Merchants. Likely from Chinese or Mongol, Koreo-Japanese sources. Also a tiny tiny North West African and South Asian contribution.
Rest assured, East Asian Genes (in tiny forms) now populate the holy land.
Few ask, so I made this thread just to clarify it.
