With an Asian mix of any kind, the strongest feature to continue through the blood line is the eye shape. It's very, very strong, and even noticable in blonde people with fair skin.
Yeah, I have been told by all kinds of people that I have an Asian eye shape, including Asians themselves. I think it comes from my Eastern European heritage, but whether from Poland or Hungary I don't know.
This thread is so incredbily helpful for me. I have medium brown hair and greenish-blueish-grayish eyes. My Polish grandmother had dark hair and light eyes.
