Continuous-variable quantification of dermatoglyphic whorl patterns: A statistical study of angular measurements

Authors


Abstract

Core(s) and triradii of dermatoglyphic whorl patterns were joined together to form triangles. Base angles of these triangles were measured (in degrees). The tangent angle at the lower edge of a ridge crossing the core—triradius line was also measured in degrees on each side of the whorl. Significant differences and similarities of these angles were investigated for unrelated Caucasian males and females by the use of Student's t- and Pearson's r-tests. Angular findings were related to the corresponding information provided by ridge counts. Similarities and differences between males and females are described.
