Abstract

Background: Forensic identification can significantly benefit from identifying the relationships between ABO blood groups, fingerprint patterns, and lip-print patterns. Aim of the work: This study aimed to explore these associations in 200 Egyptians and 200 Saudis. The main goal was to identify the most common ABO blood types, fingerprint patterns, and lip-print patterns in these populations. Additionally, this study sought to analyze any correlations between these biometric markers, providing valuable data for identification purposes. Subjects and methods: The research employed Tsuchihashi's classification for lip prints, Michael Kuchen's fingerprint classification, and the standard agglutination method for ABO blood grouping. Results: The study revealed that the ulnar loop was the most common fingerprint pattern across Egyptian and Saudi populations, with blood group A being the most prevalent. Type III (Intersecting grooves) and Type IV (Reticulate grooves) were the most frequent lip print patterns. Statistically significant associations were found between lip print patterns (Types III and IV) and specific fingerprint types (loops and whorls) across multiple quadrants. A notable relationship emerged between blood group O and specific lip print patterns (Types III and IV), indicating a potential correlation between blood group and lip print types. Furthermore, loops and whorls were more commonly linked to blood groups A and O in both populations. Conclusion: These results underscore the potential utility of combining these biometric features in forensic applications. Further research with larger samples is recommended to validate these findings and explore additional population-specific patterns.
