Analysis of palm dermatoglyphics in Taiwan indigenous populations

An analysis of a-b and a-d palm ridge counts was made from samples of people in eight indigenous Taiwan populations. Differences between hands, sexes, and populations were all significant. Bimanual differences for both counts were large, and right hand counts were consistently smaller than those for the left hand in all the populations. This is believed to be a consequence of the evolution of development, reflecting some inborn bilateral differences in function and anatomy. Sex differences, although small, were noticed. Variations between populations, ranging from approximately 7 to 19% of the total, were assumed to be genetic. The population relationships, based on dermatoglyphics, partially resembled those based on anthropometric measurements; and some aspects of their evolutionary significance were discussed.     

Dermatoglyphics of Down's syndrome patients in Malays--a comparative study

There has been no recent report on the dermatoglyphics of the Malays (normal population as well as patients with Down's syndrome). A study on the frequencies of the dermal patterns (dermatoglyphics) of the digits, palms and hallucal areas was done therefore in 40 Malay patients with Down's syndrome and 200 unrelated normal controls. Only the patients with the standard 21 trisomy karyotype were included in the study. Comparison was made with the published data on studies done in various racial groups. Significant differences of the dermal patterns were found not only between the controls but also among patients of different races.     

Quantitative digital and palmar dermatoglyphics: Sexual dimorphism in the Chuvashian population of Russia

With the aim of determining sex dimorphism among the Chuvashian population of Russia, digital and palmar dermatoglyphics of 547 individuals (293 males, 254 females) were analyzed. The sex differences for PII, TRC, and AFRC are similar to Indian and Jewish populations. Correlation coefficients between individual finger ridge counts are a little lower than in Jews but are almost equal to Indian populations. The Mantel test of matrix correlation between sexes for 22 traits shows a very good similarity. However, sex differences of palmar traits display different levels when compared with other human populations. In light of this, our evidence indicates the possible role of environmental (prenatal) factors in the realization of dermatoglyphic sex differences. The development of palmar dermatoglyphics has had a relatively longer growth period compared with fingers [Cummins, H., 1929. The topographic history of the volar pads (walking pads, tast ballen) in the human embryo. Embryol. 20, 103-126]. The palmar dermatoglyphic pattern of affinities therefore corresponds better than fingers to the ethno historical background of the populations, ascertained by numerous studies.     

Intergenerational trend of some dermatoglyphic traits in Vaidyas of West Bengal, India

In order to investigate the intergenerational change of dermatoglyphics, fingerprints of 400 individuals were collected from an endogamous caste Vaidyas of Barasat, West Bengal. Results were compared with the data of an earlier sample of Banerjee collected in 35 years before on the same community of the same area. As it is generally known that dermatoglyphics is selectively neutral, thus if no other evolutionary forces play a role, we cannot expect any change of dermatoglyphic characters after several years. In the present study, non-significant change in the frequency of pattern and more or less same PII have been observed in both sexes. But significant quantitative differences were found between the two samples. These differences may not be due to the change of intra-uterine environment, rather due to the inter-observer error of these two studies and the small sample size of the earlier study. Because though same methods were used in both studies, inter-observer variation is much possible in ridge counting than pattern type determination.     

The dermatoglyphics in the Cooley's anemia

The data concerning the digital, palmar and plantar dermatoglyphics of 108 individuals suffering from Cooley's anemia (of both sexes) are reported. The main differences found after comparison with normal individuals were a greater transversality of A line and therefore of the epidermal palmar ridges and the absence of sexual dimorphism.     

The dermatoglyphic characteristics of two isolated Bedouin groups from South Sinai

The dermatoglyphics of the Muzeina and Gebeliya Bedouin tribes, two small biologically isolated populations, leading a similar nomadic life under the specific conditions of the Sinai desert, were studied. The differences found between the studied samples concern particularly the frequencies of palmar and finger pattern types. These differences are in agreement with data on the origin of the tribes, a Negro and/or European admixture being evident in the Gebeliya dermatoglyphics. The coefficients of variation for some quantitative dermatoglyphic traits, presumably with a polygenic determination, are lower in the Muzeina than in the Gebeliya sample. Isolation and consanguinity may exert their influence on the dermatoglyphic traits influencing the frequencies of the corresponding genes.     

Dermatoglyphics in the study of genetic processes in human populations (the example of the population of Arminia)

Demographic data on the sizes of local populations of Armenia and the rates of people migration were employed for prediction of genetic differentiation level using S. Wright's f-statistics. This expected value of fe was applied for approximation of the observed level of dermatoglyphic f0d and familial f0n differentiation. Both empirical estimations of f were found to be closely to each other (f0d = 0,0616, f0n = 0,0600) and fall within the limits 0,0712 greater than or equal to fst greater than or equal to 0,0580 predicted from "island" model of Armenian population structure. The present state and direction of the genetic process in Armenia is discussed in the paper with the main conclusion that the dermatoglyphics and family surnames could be used in studies of the genetic process in human population.

Sexual dimorphism in dermatoglyphic traits and fluctuating asymmetry in Bulgarians from northeast Bulgaria

In parallel with the development of dermatoglyphics as a method of identification, data have been accumulated on the characteristics of fingerprints related to sex and ethnic origin which make up the statistical basis of this study. The aims of the present study are to determine phenotype variations in the asymmetry of dermatoglyphics in both sexes within the scope of the entire hand skin ridge system; to investigate correlations between the phenotypes; and, to assess the fluctuating asymmetry among the Bulgarian population from the region of northwest Bulgaria. The sample consists of 894 unrelated, clinically healthy individuals (480 females and 414 males) aged 18–50 years, who live in towns and villages in the northwest provinces.Finger and palmar prints were collected using rolled print (inked) method. Twenty dermatoglyphics variables of fingers and hands, separately for right and left hands and jointly for both hands, were statistically assessed. The material was processed by SPSS 12 software. The results of the present study show distinctive sexual differences. Higher values in males are recorded in finger ridge counts, the Furuhata and Cummins indices, the palm ridge counts and the overall ridge counts in all interdigital areas. Males have higher frequency values in patterns Hy, Th/III and Th/IV.

Variety of cows and sires according to types of dermatoglyphics (patterns) of the nose-labial mirror of cattle

Dermatoglyphic+ of the nasal-lip speculum presents a complex structure of skin picture on its surface. Genetics and phenetics of this character permit determining different types of dermatoglyphics, their hereditary peculiarities to be retained in generations. Different types of dermatoglyphics are established to be preserved within genealogical lines and families of cows. Differences between breeds in some dermatoglyphic elements are observed.     

Finger dermatoglyphics and their asymmetry in Bulgarian right-, mixed- and left-handers

Since Bulgarians have never been investigated concerning the relationship between handedness and dermatoglyphics, the present study was aimed to investigate the aforementioned relationship in a Bulgarian sample. Digital dermatoglyphics and their asymmetries have been studied in 870 apparently healthy students from randomly selected Bulgarian secondary schools: 264 right-handers (RH), 246 mixed-handers (MH) and 360 left-handers (LH). The whorls were significantly less frequent and the ulnar loops more frequent in RH than in the other two handedness categories. Right-handers exceeded significantly MH and LH in the ulnar fluctuating asymmetries of the first and the fourth finger pairs. As compared to the number of investigated variables and especially to the important psychological and behavioral differences between handedness categories reported earlier in the same sample, the presented significant findings are rather scarce. Nevertheless they could contribute to the accumulation of data concerning the investigated relationship and to its better understanding.
