[Influence of the X-chromosome on finger dermatoglyphic features in the Ukrainian population of Podolye].
Results of twins' and families' investigations of 19 quantitative features of fingertip dermatoglyphic patterns are presented. A conclusion has been drawn that the determinants of most of them have X-linked loci. The data were analysed in the light of the Lyon's hypothesis used in modern methods of interpretation of family correlations. The results revealed some incorrectness of the postulate of the highest connection in sister--sister pairs in the case of X-linked loci. It was ascertained that the distribution of family correlations, according to skin relief quantitative features, depends upon ethnic peculiarities of a sample: the higher the frequency of whorls in the population, the greater the probability of receiving the picture expected to occur in case of X-linked loci.
