Finger dermatoglyphics of the Tibetans



Finger prints of 156 Tibetan males and 150 females have been analyzed. Whorls are more abundant in Tibetan males (60.24%) than in females (48.67%). The index of pattern intensity shows a higher value in males (15.95) than the females (14.65).

The bimanual differences (both in males and females) are not statistically significant for the occurrence of pattern on the digits of the right and left hands. However, the difference between the sexes for the occurrence of patterns on the finger balls, are statistically significant.

Ridge counting was done for each finger. On all fingers, Tibetan males have higher ridge-counts than females. The possible tendency for the right hands to possess higher ridge-counts cannot be demonstrated statistically.

Tibetans show greater affinity with the Southern Mongoloids in the frequency distributions of pattern types on the finger balls. However, a more detailed dermatoglyphic study of all the Mongoloid populations in South East Asia, Central Asia and Far East would yield information of great value in disclosing the palmar pattern distributions among the Mongoloids.
