Abstract
Background: This study was aimed at evaluating the minutiae patterns in of Bini ethnic group of Southern Nigeria. The study was descriptive and cross-sectional with volunteers age ranging from 18-60 years. For the purpose of this study, an individual was considered to be a Nigeria of a particular ethnic group if the parents and four grandparents are of the same ethnic group.
Materials and Methods: Purposive sampling method was used for the study. The selection and collection of required parameters relied on informed consent of volunteer subjects. This was done by giving them a copy of the informed consent letter which was signed and dated. A total of 400 subjects (Males 225, Females 175) were recruited for the study. The fingerprints were obtained using print scanner (Hp G3110 Photo scanner) following Oghenemavwe and Osaat (2015) improvised model.
Results and Discussion: Distribution of total digital patterns in Bini showed that on the left hand they had the following: Ridge Ending 4399(17.1%), Ridge Crossing 2335 (9.0%), Bridge 1979(7.7%), Lake 2077(8.1%), Bifurcation 5283(20.5%), Double Bifurcation 2021 (7.8%), Dot 2015 (7.8%), Trifurcation 1938 (7.5%), Opposed Bifurcation 2029 (7.9%), Island 1723 (6.6%), while on the right hand the distributions were: Ridge Ending 4415 (17.2%), Ridge Crossing 2323 (9.0%), Bridge 1999(7.7%), Lake 2065(8.0%), Bifurcation 5303(20.6%), Double Bifurcation 2005 (7.7%), Dot 2025 (7.8%), Trifurcation 1915 (7.4%), Opposed Bifurcation 2044 (7.9%), Island 1709 (6.7%).
Conclusion: The descriptive cross-sectional study of minutiae pattern has revealed the following trend of patterns: Bifurcation 5283 (20.5%) > Ridge ending 4399(17.1%) > Ridge crossing 2335 (9.0%) on the left whereas on the right hand thus: Bifurcation 5303(20.6%) > Ridge ending 4415 (17.2%) > Ridge crossing 2323 (9.0%). This trend is in line with the stated trends for Africa, this study provides a baseline data on level 2 patterns or minutiae for the Bini people of Southern Nigeria.
