Finger prints of the Brahmin, the Kurmi, the Pasi, and the Chamar, four caste groups, were analyzed. These four caste groups, having distinct social hierarchical status in the Hindu society, show no distinct variation with one another with regard to general pattern-type distributions. Nonetheless, some variations do occur in bimanual comparisons of the reciprocal relationships of arches and whorls, which divide them into two clusters—the lower and the upper castes. The Brahmin and the Kurmi form the upper caste cluster, and the Pasi and the Chamar, the lower caste cluster.
