Abstract
AbstractThe finger prints of 138 individuals belonging to the subâcaste Rarhi Brahmin have been analyzed. In males whorls are more frequent in the right hand than the left, while it is just the reverse in case of loops and arches. Females, however, show higher frequency of loops and lesser frequency of whorls in the right hand than the left, while the arches are more frequent on the left hand of females than the right. Arches are found to be more frequent on the thumb in males, while among females it is found mostly in the second finger. The bimanual difference is statistically significant in both sexes. Right hands are found to be more monomorphic than left hands. Monomorphic hands are less frequent among females than males. In the digitwise occurrence of symmetrical combinations of different patterns, the trend is III>IV>V>I>II in males, and V>IV>III>I>II in females. Males show higher ridge counts in all fingers than do females. Ridge counts are usually found to be higher in the right hand than the left. The sex difference for mean total ridge counts is significant (t = 1.99, 0.05>P > 0.02, d.f. = 136). The bimanual difference is statistically significant for thumbs in both sexes, while the difference for the other digits is not significant.
