“…Data included the age, sex, and whether their parents are related or not. The parameters of digital dermatoglyphics have been analyzed using the methods described by (Cummins & Midlo, 1961;Holt, 1968;Penrose, 1968;Plato, 1970;Plato, Brown, & Gajdusek, 1972). The fingerprints obtained were analyzed for various qualitative and quantitative characteristics.…”

The dermatoglyphic characters can measure genetics' variations within and between human populations. This study aims to characterize the fingerprints traits in the eastern part of Libya, to analyze bilateral and bisexual differences within Libyan sub-populations. The study conducted on 1101 subjects in six cities; Benghazi, Al-Bayda, Al-Marj, Dernah, and Jalu-Ojla. Data included age, sex, and the parameters of digital dermatoglyphics have been recorded and analyzed. For statistical analysis, the frequency distributions for digital patterns were tested by chi-square, ridge were tested by student t test, and genetics distance were estimated by using the phylogenetic analysis. Total finger ridge count was significantly (p<0.01) higher in males (138.35) than females (131.46). Dindices were highest in Jalu-Ojla, Al-Bayda, Benghazi, Dernah and Al-Marj, respectively. F-indices were highest in Jalu-Ojla, Dernah, Benghazi Al-Bayda and Al-Marj, respectively; Total ridge counts were generally higher in males than females except in Jalu-Ojla and Al-Marj cities, where the latter two cities were equal. Arches and radial loops, ulnar loops were generally higher than the Whorls that were found in lower level due to the influence of consanguinity marriages, founder effect and random drift of genes. Total ridge counts were higher in males than females and in the right-hand, but not in left-hand for all the study areas. Therefore, the gender, bilateral side of the hand and the consanguinity level within the Libyan sub-population should be considered when establishing dermatoglyphic pattern indices for the Libyan population.

The highest 'pattern intensity index' in the world is found in populations located in Australia and the Eskimos in Northern America -in these populations are whorls are predominant, resulting in an average 'pattern index' above 15.5 (while in most other populations loops are most common).…”

Background: Dactyloscopy is a branch of dermatoglyphics (the study of epidermal ridges) which involves assessment and classification of fingerprint patterns for identification. All fingerprint patterns are laid down permanently from the third month of the intra-uterine life and they remain unchanged throughout the life. This is also the time when all organs in the body are finalizing their development. Therefore, a positive association of the dermatoglyphic features with different diseases like diabetes, mongolism, schizophrenia and leprosy have been well documented in the literature. The aim of the present study was to evaluate the dermatoglyphic patterns and the specific variations which may be used as a valuable diagnostic tool for early detection of diabetes mellitus. Methods: This was a prospective cross-sectional study, a total of 150 diabetic subjects and 150 non- diabetics (control) were selected from the KIUTH Western Uganda and their fingerprints were taken by the Indian ink method. The print patterns including whorls, arches, ulnar and radial loops were analysed and the variations were cross-tabulated between sex, the side of the hand and pattern distribution indexes. Data was analysed using SPSS version 26 and Dankmeijer's index and Furuhata's index were used to assess variability of the fingerprint patterns. Chi square tests was used to test for significance in variations at a confidence interval of 95%. Results and conclusion: Ulnar loops were the most predominant patterns among diabetic subjects at 35.2% followed closely by whorls at 35.1%. The most common pattern were whorls found in both hands of females at 21% (315/1500), whilst the most common pattern for male group were whorls at 17.5% (262). However, some fingers such as the ring finger completely lacked an arch pattern in both groups. The increase in arches was strongly supported by a significant increase in Dankmeijer’s index. The presence of high number of ulnar loops can therefore maybe used as an early indicator of type two diabetes.

Thirteen Iranian populations of diverse origins have been analyzed for C-line terminations, utilizing bilateral palmar prints of 3,158 individuals. Significant bimanual and male/female differences were frequently found in these populations. Interpopulational variation displayed significant heterogeneity. Distance analysis and constructed dendrograms provided separation between the populations, but the dendrograms are not in agreement with the ethnohistoric records of the populations studied._ _~
