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).
