Anthropological characterization of Bulgarian population from the region of Stranda according to dermatoglyphic data

Palm and finger patterns of the hands of 101 women and 101 men from the region of Malko Tarnovo and 102 women and 103 men from the region of Sredets were studied. 814 palm and 4070 finger patterns from 407 individuals of both sexes were investigated. The dermatoglyphic data obtained were analyzed by the method of Cummins and Midlo (1961). The dermatoglyphic material was analyzed by the method t-oriterion according to the formula of Veber (1961) in order to establish whether the differences between the dermatoglyphic traits of the studied groups from the region of Stradwa were significant. Bimanual asymmetry in some dermatoglyphic traits from both sexes of the studied population was established. Sexual dimorphism in the population from both regions according to some dermatoglyphic traits as whorls, DL10, accessorial interdigital triradili, index of Cummins and carpal axial triradii - t was established.
