Abstract

In the February issue of the journal Nature an article «Dermatoglyphic topology» by Professor L.S. Penrose [Penrose, 1965] was published. This article offered a slightly different counting system of dermatoglyphic patterns on the palmar side of the hand. It was based on counting loops and triradii for both the fingers and the palms and soles, and could be described by a simple formula. The application of this methodology revealed its practicality in family genetic analysis of patterns [Loesch, 1971] and discriminant analysis of dermatoglyphic traits in people with various forms of trisomy [Penrose, 1966; Penrose, Loesch, 1970]. The authors of the article have used this method when analyzing samples from modern populations of Kamchatka, with different variations of demographic structure. The main results of the comparative analysis of dermatoglyphics in Kamchadals and migrants have been cited earlier [Perevozchikov et al., 2016]. The following paper presents an intra-group analysis of samples that have different history of their gene pools. Triradii frequency allocations are described by the Gaussian curve. In other words, the character «total triradii» has a similar nature of variability with conventional quantitative traits. This gave us the opportunity to check out some current views on the association of dermatoglyphics with body morphology. Intra-group variability of dermatoglyphic traits (estimated number of triradii) in the two samples with different population structure in our study proved to be virtually identical. This primarily indicates the invariance of dermatoglyphic system when considering population aspect. The distribution of the number of triradii as a Gauss curve gave us an opportunity to evaluate using standard statistical methods the association of dermatoglyphic traits with some of the morphological characteristics of the human body. Association of dermatoglyphic traits (number of triradii) with morphological characteristics (absolute body size, body composition assessment and constitutional types) did not show the presence of credible links. The results of this study can be considered as preliminary, taking into account the relative paucity of our samples and a limited number of traits analysed.
