Digital Dermatoglyphic Patterns of Uturu People of Abia State

This study was carried out to find out the possibility of a unique pattern of palm and finger prints (Dermatoglyphics) among 192 adults (96 males and 96 females) of Esan origin who, at the time of this study, were residing in Esan-land-the central senatorial district of Edo state, Nigeria. The subjects were selected via multi-stage sampling technique and fingerprint determination was performed using the Indian ink methods. Palm and fingerprints were observed for the angles connecting the triradii at the roots of the fingers (a-index finger, b-middle finger, c-ring finger d-small finger and t-the most proximal triradii in the palm) taken as atd, tad and tda angles. The data collected were statistically analyzed using the Statistical Package for Social Science (SPSS) using the student t-test, chi square test and ANOVA as statistical tools. Results showed that the loop pattern had the highest frequency (61.7%) followed by whorl (24.9%), arch (12.8%) and double whorl (0.6%). The mean at...

The present study aimed at determining the association between thumbprint ridge count and sex variation among Nigerians in Calabar Municipality. A total number of 300 subjects (150 males and 150 females) aged between 12-35 years participated in the study. Conventional method of using ink pad was used to collect thumbprint of both hands and analysed using magnifying lens. The study confirmed the results of some earlier works done by other researchers on fingerprints. It further established the distribution proportions of thumbprint for both hands in both sexes for the population. The uniqueness of fingerprint to individuals was reaffirmed as no two thumbprints were identical among the 300 subjects under study. These results show that the order of prevalence are as follows; among males, in whatever combination of thumbprint pattern, whorl is the most occurring, followed by loop and arch. Among females, in whatever combination of thumbprint pattern, loop is the most occurring followed ...

Dermatoglyphic features due to its permanency, genetic influence as well as number of easily observable and measurable characters may be considered one of the most suitable parameters for population variability and have been used extensively to characterize and differentiate human populations, hence, are highly suitable for studying population variation. The aim of the study is to analyze palm prints (palm creases) among Hausas of Kano and Zaria. A total of 600 subjects comprising of 300 participants from two original Hausa metropolis (Kano and Zaria) with 1:1 male to female ratio participated. Ink method was used to capture palm prints. Chi-square was used to determine the association between the variables. The frequency distribution of palmer creases showed that in the right hand only normal creases tend to occur higher in female (203 vs 172) the two metropolis combined. Similar pattern occurs, when the two metropolis were considered separately (Kano = 97 vs 75, Zaria = 106 vs 97)...

Over the past 100 years, reliable methods of human identification have been based on finger and palm prints. The study of the patterns created by dermal ridges on the palms, soles, and fingers is known as dermatoglyphics, a term that was first used by Cummins. During the 3rd month of intrauterine life (IUL), dermal ridges start to form and fully develop by the 6th month. The dermal configurations remain the same till adulthood except forth change in size. In dermatoglyphics, analysis is done using the impression of the fingertips' papillary ridges. The palms, soles, and flexure surfaces of the fingers are where papillary ridges are primarily seen. With the opening of sweat ducts at the peak of each ridge, they form fine parallel or coiled arrays separated by a thin furrow. Anthropology, genetics, and egyptology are all included in dermatoglyphics. The impressions left by the fingers, palms, and soles are thought to result from both inheritance and environment. Nobody has the same fingerprints twice, not even monozygotic twins. Hence, each person's fingerprints are distinct and do not change over time. Medical dermatoglyphics is currently linked to a number of illnesses, including diabetes mellitus, hypertension, psychosis, 4,5 breast cancer, 6 alcohol embryopathy, 7 epilepsy, 8 and congenital cardiac disorders. 9 Previous research indicates that individuals with periodontitis, 10 dental caries, and birth defects such cleft lip and palate might have asymmetrical fingerprints.

Dermatoglyphics is the branch of science concerned with the study of prints on the fingers, palm, soles, and feet. This branch of science is an offshoot of anatomical sciences. Dermatoglyphics as an aspect of science has been studied widely by lots of ardent researchers and have been used to solve lots of problems relating to peoples' identity and ancestry. Although, dermatoglyphics can be studied at three levels (1, 2, and 3) only level 1 (arches, loops, and whorls) have been explored. 99.9% of the works on dermatoglyphics is at level 1 but no Nigerian indigenous works have been done at level 2 (bifurcations, trifurcations, bridges, ridge ending, enclosures, dots, opposed bifurcations, double bifurcations, island etc). This raises the question, what about level 2 and 3 study? There exist a large vacuum at level 2 dermatoglyphics which should be filled by researchers especially indigenous authors which will help create database for level 2 details in Nigerian population. This to large extent could be used to solve problems relating to ancestral origin which has become an issue in most African populations especially Nigeria. This review serves to help provide a step by step procedure to doing a study on dermatoglyphics at level 2 in Nigerian indigenous populations and Africa at large. The review of papers on this subject serves to expose the gap in this area as compared to the several works done at level 1 and to spore researchers to do more studies on this subject to raise an indigenous data bank for Nigerian populations

Dermal ridges express patterns of asymmetry and polarization across the fingers that can characterize human populations. They are also known somatic markers of teratogenic insults. This study documents the asymmetry and pattern polarization of dermal ridges among the Ogoni people of Nigeria. Ink prints of the fingers were obtained from 406 apparently healthy Ogoni subjects and dermal ridge pattern types of whorls, arches, ulnar loops and radial loops identified and their pattern of polarization across the ten digits established for each hand in each sex. Ulnar loops polarized preferentially to digits III-V; arches to digits I-II; whorls to digits I, II, and IV; and radial loops to digits II. Female subjects had higher counts of arches (P <0.001), radial loops and ulnar loops (P>0.05) than the males, while male subjects had higher counts of whorls (P<0.01) than the females. The findings of this study form useful baseline data for subsequent longitudinal cytogenetic studies on the Ogoni people.

Fingerprints are classified and documented on the basis of ridge patterns. The impressions made by the pattern of any individual remain unchanged throughout life. The study was carried out on 400 individuals among which 200 were males and 200 were females subjects having different ABO blood groups, all the 10 fingerprints were divided into loops, whorl and arches. The results showed that majority of the subjects belonged to blood group O. The finger print pattern of loops had the highest frequency while arches were the least. Blood group O were mostly associated with the loop pattern while AB had the least frequency in all the fingerprint patterns. Males had the highest number with the loops and whorls while females had the highest number of arches. It was concluded that there was an association between distribution of fingerprint patterns, blood group and gender and thus prediction of gender and blood group of a person was possible based on the fingerprint patterns.

Dermatoglyphics connotesfriction ridges on the skin, visibleon fingers, toes, and palms of individuals. These epidermal ridges, especially finger prints have proven to be viable physical features in criminology, medical diagnosis and genetic studies. Handedness; observed as an individual's preferred use of a particular hand over the other, for daily activities has been attributed to the uneven distribution of fine motor skills between the left and right hand. We conducted this study in a bid to assess the distribution of whorls fingerprint patterns in relation to Handedness amongst a set of students in North-Central Nigeria for Identification. The study had 279 respondents via purposive sampling approach, with 148 Left handed and 131 right handed people. Edinburgh Handedness inventory was used to evaluate handedness and respondents performed 14 uni-manual Tasks to ascertain handedness. Fingerprints were analyzed, using a laboratory magnifying lens to determine the print patterns and their distribution among the respondents, after obtaining them via the ink and paper method. Collated data was analyzed via Mini TAT Statistics for Windows (version 16) and Microsoft Office Excel 2016. The Left hand in Right handed people had 51.6% whorls while the right hand had 50.8%. Similarly, 56.8% was the distribution of whorls found on the left hand in Left handed people whereas the right hand had 60.4%. T-test analysis of the obtained result showed no statistically significant relationship of the whorl fingerprint patterns and handedness (p>0.05).

Introduction: Genetically, genes located close to each other on the chromosome have greater chances of being inherited together, therefore influencing each other. Technological deficiencies may not permit genome mapping, however the traits that are produced from such genes are likely to show strong associations. Therefore, this study was carried out to investigate the association between index finger and lip print pattern among Nigerians. Materials and methods: A total of 450 subjects comprising of 212 (47%) males and 238 (53%) females selected from Port Harcourt were used for this study. Oghenemavwe and Osaat digital finger and lip print capture technique were adopted for this study. Clearly obtained prints were transferred to a laptop via USB connection and the prints were magnified using the zooming tool. Finger prints were determined by observing the primary configuration (arch, loop and whorl) while lip prints were obtained by dividing the lip into four quadrants (upper quadrant [UQ] and lower quadrant [LQ]; L & R) which were independently accessed for the predominant lip print using Suzuki and Tsuchihashi's classification (Types; I, I', II, III, IV, and V). Statistical analysis was performed using XLSTAT (Addinsoft Version 2015.4.01.21575). Chi-square was used to determine the trend in the distributions, while lip print pattern and index finger print were cross-tabulated and evaluated for association. P<0.05 (at 95% confidence level) was taken to be significant. Results: The predominant print type on index finger was loop; 174 (38.7%) on the right (R) and 186 (41.3%) on the left (L) which were sex determined for both fingers (R; χ 2 =7.05, p=0.03 and L; χ 2 =6.39, p=0.04). The lip print exhibited predominant differences in the upper and lower lip print. The upper lip was predominantly type III (243 [27%]) while the lower lip was type I (319 [35.4%]). The distribution in male and female was significantly different, only for the right quadrant of the upper lip (χ 2 =16.39, p=0.01).When the index fingerprint distribution was related to lip print, loop co-related more with Type III at the upper lip (URQ; 30.5%, ULQ; 29.3%) while the lower lip had a mix of Type I and whorl (LRQ; 38.6%) and loop (LLQ; 36.8%). The associations were not significant (P>0.05). Conclusion: The distribution of the print patterns on the index finger and lips are independent of each other and therefore, the inheritance of lip print and finger print cannot be said to be genetically linked.

The present study was aimed at determining the existence of FA in Hausa populations using thumbprint minutiae. The participants included 112 males and 105 females of Hausa Ethnic descent, aged between 18-25 years. The minutiae of the plain thumbprints were determined from a circle with radius that cut across the nucleus of the fingerprints. The result showed that in signed asymmetry bifurcation, crossbar, break, point/dot into ridges and point/dot between ridges exhibited sexual dimorphism. The left ward asymmetry in male was exhibited in bifurcation, cross bar, trifurcation bifurcation, break, bridge, opposite bifurcation, in "M" convergence, in "M" bifurcation and Point/Dot into ridges. Similarly, in female bifurcation, trifurcation bifurcation, enclosure big, opposite bifurcation, convergence, in "M" bifurcation and return exhibit left ward asymmetry. For absolute and composite asymmetry the significant differences was observed in end, enclosure (small), bridge and return. In the entire minutiae types only ridge bifurcation exhibited directional asymmetry in males and six other minutiae types in females. In conclusion, the presence of sexual dimorphism in thumbprint ridge minutiae was demonstrated in the present study. The leftward asymmetry was observed in both sexes in different types minutiae. Females were observed to exhibit directional type of asymmetry more than the males in this population.

The present study was carried out to understand the genetic relationship if any, among different Indian populations using classical dermatoglyphic markers in 250 postgraduate students. Finger print patterns were collected on a white paper using a non-spreading blue ink-pad. The other traits were recorded by direct observation. The ridges were counted and patterns were identified using glass hand-lens. Statistical analysis was done using student t-test, two-way anova (multivariate) and chi-square test of significance using ANALYSE-IT software. Phylogenetic analysis was carried out using PopGen 32 and MEGA 4 software. Significant variations were found for total ridge count between North vs. East cohort (p<0.001) and East vs. West cohort (p<.001). Interestingly, 55% of the participants from Northern cohort had dominant allele for hand clasping and thumb extension traits, while 55% participants of South cohort have recessive allele for the same. Interestingly, blood group "O" and "AB" were found significantly ((p= 0.07) associated with "whorl" and "loop" fingerprint pattern types in each cohort.
