My ethnicity according to 23 and Me is 95% Ashkenazi, which is a European/Middle Eastern ethnicity particular to Jews. According to 23 and Me, I have one full blooded North African relative in recent history and even a full blooded Swede, but very little Eastern European ancestry per se, even though my grandparents lived in Russia, Poland, and the Ukraine prior to coming to America. So you can see that contrary to what I've read in comments below, being Jewish *IS* an ethnic identity, and my reading tells me that Ashkenazi and Sephardic Jews have more in common with each other DNA-wise than they do with the cultures in which they may exist. That said, I have very "overly curly" hair. Got teased as a child, before anyone knew how to tame curls. Wore my hair short and curly for years. Now 70, I use a round brush and flatiron. My dad had straight hair while my mother's family contributed the curls. and That's probably because Dad had some Yakut DNA, and the Yakut people in Siberia have straight hair, while my mom's side was probably more from the Mediterannean, and they tend to have curlier hair. So maybe Jewish hair isn't so much about Jewish genes as the fact that Jews came from certain parts of the world where curly hair was more prevalent.
