Based on the existence of the two genetic complexes determining finger prints (SU - spiral and SR - despiral), the two-compartment multithreshold polygenic model for systematization of finger prints has been proposed. It was found that the radial loop is genotypically not identical to the ulnar loop, as it was thought before, but differs very much from the latter by its print. The relative height of thresholds for each of 10 fingers has been measured. The two embryonal gradients have been established: one with a positive, and the other with a negative correlation between the threshold heights.
