[Inheritance of human fingerprints]

Polygenic threshold model of finger dermatoglyphics inheritance is worked out on the basis of family and population data. According to the model, ulnar loops are subthreshold patterns, which transforms into whorl or arch under the control of SU and SR gene complexes. Epistasis-hypostasis interactions take place between genes of SU and SR complexes. Classification of phenotypes for finger dermatoglyphics is offered and the frequency of these phenotypes in three populational samples of Kiev is studied.
