Регіональні особливості пальцевої і долонної дерматогліфіки та їх зв’язок із показниками особливостей особистості практично здорових чоловіків України

Abstract

The study is devoted to the dermatoglyphic substantiation of the criteria for determining the belonging of practically healthy men aged 19-35 years to one or another administrative-territorial region of Ukraine and the relationship of indexes of finger
and palmar dermatoglyphics with indicators of personality characteristics.
For the first time, qualitative and quantitative features of finger and palmar dermatoglyphics of practically healthy men in the whole country have been established and the contribution of each of the 5 territorial-administrative regions of Ukraine to the general phenotypical picture of dermatoglyphics of the male population of Ukraine, reflecting the formation of regional gene pools and the contribution of each nation, has been
determined.
It is demonstrated that the basic genetic landscape of the male gene pool of
Ukraine, according to finger dermatoglyphics, form the central and northern regions of
the country, and according to the palmar dermatoglyphics – quantitative indicators of
the central and western regions and qualitative indicators of the southern and northern
regions. At the same time, the association of the percentage distribution of the contribution of individual administrative-territorial regions in the overall picture of finger (but not palmar) dermatoglyphics of the country with the indices of inbreeding calculated by surnames Gorpinchenko M. and Atramentova L. (2015) is established.
Men's dermatoglyphics were also identified individually for each of the five administrative-territorial regions, allowing them to identify a person's regional identity. It has been established that 22.22 % of finger dermatoglyphic indices are attributed to a person in the central or southern regions of the country; central or eastern – 20.37 %; central or western – 15.74 %; north or south – 17.59 %; north or west – 16.67 %; northern or eastern – 15.74 %; western or eastern and southern or eastern – 12.04 %. Finger dermatoglyphics does not differentiate administrative-territorial local groups of men between regions: north and center and south and west. High taxonomic value for intrapopulation differentiation of the local level have: types of patterns with high intensity of ridge formation and capacity of the pattern, especially III and IV fingers of the right hand and I and II fingers of the left hand.
The administrative-territorial features of the palmar dermatoglyphics of men from
regions with high heterogeneity of features are described by 20.0 % of indicators as criteria for a person's identity in the central or eastern regions; 16.9 % of indicators – to the central or northern and northern or western ones; 15.4 % of indicators – to the western or eastern regions of Ukraine. The complex of features of palmar dermatoglyphics that distinguishes men of the central region from the east includes the pattern of hypotenar, tenor, I and II of the interdigital space, the size of the dat angle, the Cummins index, additional axial triradius; central from the north – the pattern of hypotenar, tenor and IV interdigital space, the size of the angles atb and ctd, and the ridge count c-d; north from the west – pattern of the II interdigital space, additional axial triradius, angle сtd size and ridge count c-d; west from east – hypotenar pattern, additional axial triradius, size of angles atd, atb and dat, length of segment c-t.
Men from the northern and eastern (6.2 % indicators), southern and western (6.2 % indicators) and southern and eastern (7.7 % indicators) regions of Ukraine show significant affinity according to palmar dermatoglyphics. Among the features of palmar dermatoglyphics, the following dermatoglyphic complexes of features have a high taxonomic value for the intra-population differentiation of regions with low heterogeneity: for the northern and eastern ones – the pattern of the II interdigital space, the additional axial triradius and the size of the angle atd; south and west – hypotenar
pattern and ridge count a-b; south and east – the size of the palm angles atd and
dat, the length of the segment c-t. In general, among the features of palmar dermatoglyphics, high taxonomic value for intra-population differentiation of the local level have: localization and saturation of palm patterns, size of palm angles, presence/absence of additional axial triradius, length of segment c-t, Cummins index.
For the first time, reliable discriminatory models of belonging practically healthy
men to a certain administrative-territorial region of Ukraine have been constructed
which, depending on the features of indexes of finger and palmar dermatoglyphics,
which correctly cover representatives of these regions from 67.8 to 82.9 % of cases
and, in most cases, have slight discrimination level (Wilks lambda statistics range from
0.747 to 0.879). The highest levels of discrimination were found between northern and
southern men (Wilkes lambda statistics equal to 0.665), northern and eastern (Wilks
lambda statistics equal to 0.658), and western and eastern (Wilks lambda statistics
equal to 0.640) regions of Ukraine. The most common discriminant variables between
men in northern and other regions of Ukraine are the type of pattern on the fingers of
the right hand and the asymmetry of the ridge count of lines a-b and c-d; between men
of southern and other regions of Ukraine – the type of pattern on the fingers of the right
hand and the asymmetry of the ridge count of the palmar lines; and between the men of
the central, western or eastern regions of Ukraine, the type of pattern on the fingers of
the left hand.
For the first time the peculiarities of reliable, mostly single, direct and reverse weak forces, correlations between indices of personality characteristics and dermatoglyphic indices of practically healthy men of Ukraine were established. It is shown that the multiple nature of significant correlations is observed only between the majority of indicators of the Rotter subjective control scale and the presence of a pattern on the tenor of the corresponding palm (on the right hand r = 0.31 – 0.37; on the left hand r = 0.22 – 0.29); almost half of the indicators of the Rotter subjective scale and pattern type asymmetry on the first finger (r = 0.23 – 0.27); Lusher gray index, and ridge count of right hand I, III, and IV fingers and left hand I, II, fingers, total ridge count, and left hand delta index (r = -0.23 – -0.28).
For the first time, using factor analysis, the main factors that have a significant
influence on the personality traits of practically healthy Ukrainian men are identified –
the "finger ridge count" (which includes virtually all the finger ridge count and delta
index of both hands; the proportion of variance is 13.22 %) and the "magnitude of the
atd angle" (which includes the magnitude of the atd angle on both hands; the proportion of variance is 10.66 %). The analysis of the obtained relationships showed that with increasing indicators of the factor "ridge count of the fingers" the degree of probability of growth of indicators of neuroticism according to Eysenck, situational (reactive) and personal anxiety according to Spielberger, accentuation of the character of the emotional and excitable types according to Shmishek, subjective control in the field of
health and illness according to Rotter, black and gray color according to Luser decreases, and indicators of accentuation of the character of the anxious and demonstrative types by Shmishek, general internals and the level of subjective control in the field of education (professional) relationship by Rotter, blue and blue-green color by Luscher – increases; with increasing factor "magnitude of atd angle" the degree of probability of growth of indicators of neuroticism according to Eysenck, situational (reactive) and personal anxiety according to Spielberger, accentuation of the character of the emotional, anxious and arousing types by Shmishek, blue color according to Luscher increases, and indicators of accentuation of the character of the demonstrative type according to Shmishek, the general internality level of subjective control, in the field of educational (professional) relations and in the field of health and illness according to Rotter, blue-green, black and gray color according to Lucer – decreases.
