[Dermatoglyphic characteristics of the Czech population]

Statistical processing of results obtained from dermatoglyphic digital patterns of the Czech population--110 women and 130 men of a reference group--revealed the tendency of more complex pattern formation in men and a tendency of simple pattern formation in women. As regards the frequency of vortices, the differences are significant at the 1% level (in men they form 24.15% patterns, while in women 14.27%). There is also a significant difference in the ratio of arches (1% level of significance)--frequency in men, 5.85%, is lower than in women--11.69%. In the general evaluation the ulnar loops differ only at the 5% level of significance (in men 58.85% and in women 63.18%). The frequency of radial loops and double loops differ insignificantly. The results indicate a greater trend of asymmetrical patterns in men than in women. In investigations of the sexual dimorphism the attained numbers of statistical differences differ by fingers--the most widely different values are recorded in the index fingers and the least different ones in the middle fingers. The number of statistical differences by sex differs also by patterns: most in vortices and arches and least in double loops.
