Collect data was analyzed through chi-square in SPSS ver. 26.Results: Total 440 participants were included of which majority were male (53.4%) compared to female (46.6%). Type I' lip prints showed a significant gender differences (p <0.05), with a higher prevalence in females. For fingerprints, the right thumb Arch pattern was also significantly associated with gender (p<0.05), while Loop patterns exhibited a notable preference in males (p<0.05). Relationship between lip prints and blood groups were significant for Type I’ (p<0.05) and Type II (p<0.05).Conclusion: Type I’ lip prints demonstrate strong relation with both A+ and AB+ blood type. This study observed a dis-tinct fingerprint patterns in right thumb arches and loops that show differences between male and female participants and point toward variations in gender-specific characteristics.Key words: ABO Blood Groups, Forensic Science, Finger Prints, Lip Prints, Gender Determination, Cheiloscopy.
