I recently learned a feature that supposedly indicates whether one is of Han descent or not.
1) First, look at your left foot
2) Look for the leftmost front corner of the toenail on your smallest toe (i.e. pinky)
3) Is there an additional point that grows out? (This only applies if you haven't clipped your nail recently)
I do, and apparently all Han people are supposed to. This was told to me by an old friend of my father, and when I told my father he said he had heard about this from other people long ago. One of his friends who has lived among the hill tribes in Burma actually carried out a survey of people's toenails to see if there really is a difference. Supposedly he also found that the tribespeople all didn't have the extra point, but the Han people all did. My father showed me the point on his toenail, while my mother said she always just clips hers off. That's what I've normally done too - I thought it was just a deformity in my toenail.
As far as I can tell, a "split pinky toenail" as the trademark of Han people remains folklore that has not been proven through genetic studies. I'm also not sure if it's supposed to be only the left foot toenail, or both feet. More discussions here: http://www.cantonese.sheik.co.uk/phorum/read.php?1,9363
