The frepuency of hair at the middle segment of phalange was significantly different between male and female (male>female, P<0.05), and the occurence of hair at the middle segment of the Yao was much lower than that in the White race, Indian, Japanese, Tibetan, Uygur (P<0.01 ), but a little lawer ther than that in the Han, Dong, and a little higher than that in the Zhuang, Tujia (P>0.05).
