General phenotypological picture of the finger dermatoglyphics of Ukrainian men: the contribution of individual regions

The formation of regional gene pools and the contribution of each of them to the formation of the population of Ukraine remains an actual topic of the present. The purpose of the study is to assess the contribution of each of the 5 territorial-administrative regions of Ukraine to the overall phenotypological picture of the finger dermatoglyphics of the male population of Ukraine. By the method of H. Cummins and Ch. Midlo conducted a dermatological study of 400 practically healthy men from 5 administrative-territorial regions of Ukraine. Statistical processing of the obtained results was carried out in the package “Statistica 6.1” using nonparametric methods. It was established that among practically healthy men of Ukraine without administrative-territorial distribution and representatives of various administrative-territorial regions 37.96% of reliable or tendencies of differences of information indicators of finger dermatoglyphics were revealed out of 108 analyzed parameters. The best information ability of quantitative (47.83%) indicators of finger dermatoglyphics was proved in comparison with qualitative (35.29%) indicators. The greatest number of differences in the signs of finger dermatoglyphics is established between men without division into administrative-territorial regions and men, residents of the southern (11.11%), eastern (10.19%) and western (8.33%) regions of Ukraine. Less number of differences from the overall picture of the country are found in men in the northern region, its rates significantly differed almost at the level of error and amounted to 5.56%. Indicators of finger dermatoglyphics of men in the central region in general do not differ significantly from those in general in Ukraine. Thus, the dominant component in the general phenotypological picture of finger dermatoglyphics of the male population of Ukraine has a central region whose rates were not significantly different from the country’s total, and to a lesser extent, the dermatoglyphics of the northern region. The obtained results indicate that the main genetic landscape of the gene pool of Ukraine, according to finger dermatoglyphics, forms the central and northern regions of the country.
