Palmar and digital dermatoglyphic patterns in the Ndokwas of Delta State, Nigeria

Abstract

We determined asymmetry, complexity and pattern polarization of dermal ridges and palmar variables of atd angle, a - b ridge count and total finger ridge count of dermal ridges among the Ndokwa people of Nigeria. 4(X) healthy students who are Ndokwas were studied. Ink prints of their fingers and palms were obtained. Counting and classifying of Palmar and digital ridge pattern configurations of arches, loops and whorls was based on standard techniques. Ulnar loops polarized preferentially to digits III, IV and V and radial loops to digit II. Female subjects had higher counts of radial loops (p < 0.001) than the males. Male subjects had a higher whorl count than the females (p < 0.05). Our findings form useful baseline data for subsequent longitudinal cytogenetic studies on the Ndokwa people.
