Dermatoglyphic genetic traits and digital patterns in Jubian and Upper Egyptian populations

ABSTRACT

Finger and palm prints of 200 males and 200 females of Jubian population were examined in an attempt to establish their dermatoglyphic configurations. The results were compared with those of a similar number of Upper Egyptians. Both sexes of both populations had the same formula of total pattern frequency on finger tips [Lu W A Lr]. The right thumb in Upper Egyptian males and right index in both Upper Egyptian sexes showed a higher frequency of whorls than ulnar loops. Radial loops showed a higher frequency of whorls than ulnar loops. Radial loops showed also a higher frequency than arches in the left index and left little fingers in Upper Egyptian males and right ring in Upper Egyptian females. In Jubian females, arches were more frequent than whorls in the left ring finger. The Jubian population showed significantly lower values of the right hand, left hand and in total finger ridge counts in both sexes compared with upper Egyptians. Unlike the Upper Egyptians, the Jubians showed significant bisexual difference in the a-b ridge count and atd angle in both hands
