Maybe it’s more of a family than a race. Racially what is the difference between an Arab and an ethnic Jew?
We are a Tribe.

‘The Invention of the Jewish People’ Shlomo Sand and Yael Lotan
Not an easy read but informative and well researched.
Shlomo Sand studied history at the University of Tel Aviv and at the École des hautes études en sciences sociales, in Paris. He currently teaches contemporary history at the University of Tel Aviv
The comments associated with this scholarly work are fascinating. He hasn’t been killed yet.
"Racially" not much.
Many Jews lived in Arabia, Mesopotamia etc. and definitely Arabs will have some Jewish blood. Ditto for indians from Maharashtra (Bene-Israeli) and Ethiopians (probably more so for Ethiopians), Poles and Italians(due to centuries of inter-mingling) and to a lower extent Spaniards/Portuguese and Germans
Those without this blood are mostly going to be Russians (due to strict rules -- but I could be wrong based on Khazar history), English (as the Jews were kicked out early and when they were allowed back were strictly segregated) and Scandanavians (low interaction) and sub-Saharan, south of Ethiopian Africans and South-East Asians and Chinese/Japanese/Koreans
