Introduction: Dermatoglyphics refers to the study of naturally occurring ridge on the planter surface of hand and foot of primates and other animals. Dermatoglyphics is a polygenic trait and is not duplicated among species even among monozygotic twins.The Ijaw’s are located predominately in the Niger Delta with fishing as their main stay of economy.Aim:  To determine the frequency distribution and gender differences of dermatoglyphic patterns of the Ijaw ethnic group in Nigeria.Methodology:  A total of 500 subjects were randomly selected to establish their digital and palmer dermatoglyphics by counting and classifying their ridge patterns based on standard technique.Results: The highest dermatoglyphic pattern frequency was radial loop (RL) 2.7±1.22, with least occurrence of ulnar loop pattern (UL) 1.37±0.60. There were no significant total finger ridge count (TFRC) and pattern intensity indices (PII) between sex P>0.05. Female subject had a significantly higher mean ATD angle and a-b ridge count than their male counterpart P <0.05.Discussion: There was a prevalence and elevated total frequency of radial loop and a diminution of whorl digital dermatoglyphic patterns; this finding is unique for this study population since most African studies among Nigeria ethnic group has ulnar loop as a predominate digital pattern. Also, sexual dimorphism was shown to exists in total finger ridge count (TFRC) and pattern intensity indices (PII) among the sampled subjects, however female subjects were reported to have higher mean ATD angle and a-b ridge count when compared to their male counterpart, this was statistically significant at P<0.05.Conclusion: This study has reported pattern frequency and gender asymmetry of digital and palmer dermatoglyphics traits of the Ijaw ethnic group.

AbstractDermatoglyphics have been widely studied and have been shown to vary across different ethnic populations. The present study investigates the dermatoglyphic patterns among adolescents of the Ebira ethnic group through selected dialects. A total of 591 subjects, both males and females, participated in the study. Prints were collected by conventional ink and roller method and read using hand magnifying lens. Analyses were performed using descriptive statistics, analysis of variance (ANOVA), t-test, and the chi-squared test. P-values < 0.05 were considered statistically significant. The result of the study showed that the three dialects had similar distribution of fingerprint patterns in the order ulnar loop > whorl > arch > radial loop. The fingerprint pattern showed strong statistical association with gender both within and across the dialects (p < 0.001). The palmar crease of the subjects showed the normal palmar crease to be the most prevalent (87%), followed by the Sidney crease (9%), and the Suwon crease (4%) being the least prevalent for both palms across the dialects. There was strong association with palm crease type and gender, with p < 0.001. The triradii angles of the palms revealed a mean value of acute angles. Females had significantly higher mean atd angles compared with male subjects, while males had significant higher mean dat angles compared with females for the three dialects. The adt angle, however, showed no significant mean difference between males and females. In conclusion, the present study evaluated the fingerprint patterns, the palmar creases and the triradii angles conforming anthropological similarities within these three dialects. However, gender differences were observed for the three dialects, with Ebira-Tao and Ebira-Etuno exhibiting shared patterns.

The genetic and environmental contributions to determine digital dermatoglyphic traits were investigated by using female dizygotic and monozygotic twin pairs to estimate heritability indexes (h2). The evaluated sample was composed by 20 monozygotic twin pairs and 13 dizygotic twin pairs. A significant heritability (h2 = 0.65 to 0.96) was observed for 12 dermatoglyphic characteristics (delta indexes and ridge counts for right hand, left hand and both hands, and ridge counts for most individual fingers). A negative correlation between the ridge counts and heritability indexes from individual fingers was found for the left hand, which appears to be associated to a higher arch pattern frequency in most left-hand fingers, since this frequency was negatively correlated with ridge counts and positively correlated with heritability indexes. Heritability indexes of right-hand fingers were positively correlated with loop pattern frequency and negatively correlated with whorl pattern frequency. The low heritability of ridge counts from left thumb, ring and little fingers (h2 = 0.11 to 0.32) indicates a higher chance that the chorion type had an influence in the intra-pair variance of monozygotic twins. Results confirmed the predominant genetic influence on the total ridge count. The heritability indexes varied in up to 8 times between different fingers and its association to ridge counts and pattern frequency was very variable between hands, evidencing that the use of dermatoglyphic traits from individual fingers as indicators of genetic influences to other human traits should consider this variability.

The present study describes the initial phase of the Thai Twin Registry (TTR) in Khon Kaen University, a pioneer research university located in the Northeast of Thailand. The initial steps of the study included the analysis of dermatoglyphic information in Thai twins for answering the research question: Are monozygotic (MZ) and dizygotic (DZ) twins different in dermatoglyphic variables? Subjects were 212 twin pairs (81 MZ and 131 DZ), consisting of 155 males and 269 females. Four types of fingerprint pattern (FP) — that is, arch, radial loop, ulnar loop, and whorl — were classified and analyzed and compared between MZ and DZ twins. The arch radial loop and whorl frequencies differ between MZ and DZ twins. When comparing FP in each finger, only the right little finger shows a statistically different FP, while the FP similarity average from 10 homologous fingers of co-twins was greater in MZ than DZ twins. By using the Area Under the Receiver Operating Characteristic curve analysis, the MZ twins could be differentiated from DZ twins by the FP similarity. Summarizing, this valuable report about TTR was conducted by analysis of FP data, which indicated that the MZ and DZ twins exhibited FP pattern and FP similarity differences. Other dermatoglyphic studies of the existing FP database, such as finger ridge count, finger ridge density, and minutia, will be considered for ongoing research at the TTR.

Phalanx distal pattern is a curve appeared and formed an unchangeable pattern unless it is caused by a severe trauma. Phalanx distal patterns are classified into 9, namely, Plain Arch, Tentarch, Ulnar loop, and Accidental. In order to find out suspect’s identity, Indonesia Autometic Print Identification System (INAFIS) used 3 stages, which one of them is to determine pattern variation. Phalanx distal fingerprint on human can be utilized as to identify a person, whereas no one has resembled phalanx distal fingerprint even on twins. In this research, the researcher analyzed tendentious pattern variation of phalanx distal pattern on kleptomaniac in police resort office Jember. Generally, phalanx distal fingerprint pattern found on kleptomaniac tendentiously has unique pattern plain arch as the third most apparent pattern beside unlar loop and whorl, meanwhile it was found radial loop on non-patient as the third most apparent beside unlar loop and whorl which generally was phalanx distal fingerprint.

BACKGROUND: Dermatoglyphic patterns that are often utilized in judicial and legal investigations are valuable in diagnosis of many diseases related to genetic disorders. Caries, being infectious in origin, might be related to genetics as well. Hence, these patterns are of significance in predicting caries development.MATERIALS AND METHODS: DMFT (decayed, missing, filled teeth) score of 300 female subjects within the age group 0f 18-25 years were recorded and accordingly divided into 3 groups of 100 each; group 1 (DMFT score=0), group 2 (DMFT score < 5) and group 3 (DMFT score ≥ 5). Dermatoglyphic patterns were recorded using Cummins and Midlo method. pH meter was used for recording salivary pH accurately. Fingerprint patterns and salivary pH recorded were correlated with DMFT scores of subject and control groups. Statistical analysis was performed using ANOVA and Chi-square tests (P < 0.05).RESULTS: The mean salivary pH was least in group 3. The predominant dermatoglyphic pattern observed in groups 1 and 2 was loop pattern whereas, in group 3, whorl pattern was predominant. The TFRC (total finger ridge count) was higher in group 3 compared to the other two groups.CONCLUSION: Caries-free people showed inflated frequency of loops, whereas subjects with high decay score had additional share of whorls. The TFRC was higher in individuals with high DMFT score, and salivary pH was inversely proportional to the DMFT score.

AbstractFingerprint patterns are unique patterns made by friction ridges and furrows present on the pads of finger tips. Uniqueness and persistence are the two underlying features of fingerprint patterns. Aim of this present study was to determine the differences in the incidence of fingerprint patterns in intellectually disabled children compared to normal healthy children. Intellectual disability is a generalized disorder appearing before adulthood and is characterized by limitations in both intellectual functioning and in adaptive behavior. The present study comprising of 120 students (60 intellectually disabled and 60 controls) was carried out in Pediatrics outpatient department, Yenepoya Medical College and Hospital, Mangalore. The incidence of the four fingerprint patterns (Ulnar loop, Radial loop, Whorls and Arches) were determined in both the groups. Ulnar loop pattern had the highest incidence in both the groups and the least incidence was shown by arch pattern. There exists difference in the frequency of the fingerprint patterns in males and females of both the groups. The study was conducted to observe for any difference in the incidence of fingerprint patterns between intellectually disabled and normal children.

This study examined the attitude toward parental control of mate choice, and two potential factors related to this, that is, opposition to out-group mating and ethnic identification, in the five major ethnic groups from the Republic of Surinam ( n = 500), that is, Hindustani, Creoles, Maroons, Javanese, and people of Mixed descent. Some of the main differences between groups were the following: Hindustani and Maroons had a more positive attitude toward parental control than all other groups, Hindustani were more opposed to out-group mating than all other groups, and Maroons expressed more identification with their ethnic group than any other group. Women, as compared with men, valued parental control of mate choice more and expressed more opposition to out-group mating. All effects of ethnic group and gender were independent of the demographic variables on which the groups differed significantly. A positive attitude toward parental control of mate choice was associated with more opposition to interethnic mating and with more ethnic identification. The results are discussed in the context of research on the persistence and independence of cultural differences.

Background: The uniqueness of fingerprints have made it possible for anthropologist to carry out studies on ethnic differences, heritability and linguistic relationships among individuals. The study aimed at               investigating and comparing fingerprint patterns of the Itsekiri and Urhobo ethnic groups in Warri, South Southern Nigeria. Methods:  A total of 30 males and 30 females each from the Itsekiri and Urhobo tribe were investigated. Fingerprints of participants were obtained with a Hewlett placard G4010 fingerprint scanner. Chi-square and Mann Whitney U test were used to test for an association between non parametric variables, significance was accepted at P<0.05. Results: Finding showed that the ulnar loop was the most predominant pattern in the studied population. Fingerprint patterns and total finger ridge count showed dimorphism among the Itsekiris’ as compared to the atd angle of the left fingers seen in the Urhobos’ (p = 0.021; 0.010; 0.038). Significant differences were observed in fingerprint patterns of the right and left thumb alongside the right middle finger among the respective tribes (P=0.047; 0.007; 0.024). Findings also showed a significant difference in TFRC and atd angle between the Itsekiris’ and Urhobos’ (P= 0.010; 0.002; 0.027) . Conclusions: The ulnar loop was dominant among the Itsekiri females and Urhobo males while the whorl and arch patterns were  frequent in the Itsekiri males and the Urhobo females.  Keywords: Delta State; fingerprint; Itsekiri; Urhobo; Warri.

Objective: To determine the proportion of women that wanted to know fetal gender at ultrasound, characterize them and document reasons for wanting to know fetal gender. Methodology: A cross-sectional study on consecutive pregnant women at 20 weeks or more gestation that presented for prenatal ultrasound at a private hospital in Nigeria from May to December 2005. Results: Of the 1135 women, 167 (14·7%) sought to know the fetal gender. Significant independent factors included ethnic group, as women from the predominant Hausa–Fulani were less likely when compared to those of other ethnic groups (OR: 0·4, 95% CI: 0·2–0·7). Women with tertiary education were 6·6 times (OR: 6·6, 95% CI: 3·3–13·2) more likely. Women with a previous male baby were 30·6 times more likely (OR: 30·6, 95% CI: 13·6–68·5), while those with previous female baby were 54·3 times more likely (OR: 54·3; 95% CI: 23·4–125·8) to seek fetal gender. Main reasons for seeking fetal gender were preference for a particular fetal gender (57%); what wears to buy for the baby (24%) and curiosity (18%). Conclusion: About 15% of the study group requested to know fetal gender and it was associated with ethnic group, maternal educational level and gender of the previous baby. The most common reason for wanting to know fetal gender was the desire for a particular gender.
