Each print was divided into ten compartments for final analyses of lip prints. Chi-square test was used to test for association between the season of birth and lip prints. Statistical significance was considered at p 0.05) with lip prints in all compartments. In conclusion, the environmental factor considered in this study (season of birth) has no influence in the determination of the lip prints patterns.
