| Abstract: | A hypothesis claiming that the total phenotypes of finger patterns are controlled by three independent two-allele loci A, L and W with the complete dominance in each was analysed in this work. By means of the population genetics methods, non-accordance of the hypothesis examined to the observed distributions of total phenotypes A, L, W, AL, LW, ALW was revealed on the material of five populations (3060 men). On the basis of the segregation analysis method applied to 210 complete families (the total number of children-532), the hypothesis of one-locus heredity with the complete dominance of total phenotypes A and W was rejected, the reliability of this conclusion being 0.999 and 0.95, respectively. The hypothesis of the L pattern being genetically controlled by one locus with the complete dominance gave, when examined, the contradictory results, due to monomorphism of the character. |
