DIGITAL HAIR DISTRIBUTION OF THE DONG PEOPLE,GUANGXI

The frequency and pattern of hair distribution on the phalanges of the hand were exa-mined in the Dong with a total number of 279 people including male and female pupils and peasants aged 18 to 50, living in Mapan village, Sanjiang County, Guangxi. The results ob-tained are similar to those reported in the literature. No hair exists on the distal phalanges, whereas it exists on the proximal and middle phalanges. As to the incidence of hair on the middle phalanx in the Dong nationality of Guangxi, it is much lower than that in the Ame-rican (White), the Bengali (Indian), the Japanese, and the Han nationality of China, and it is a little higher than that in the Africans (Nigerian). The incidence of hair on male fin-gers is higher than that on the female. Hair distribution on both hands in the same indivi-dual is fundamentally symmetrical.
