Abstract

Background: Cheiloscopy is a quick, simple, reliable, and emerging forensic method for the identification of sex. Inheritance pattern has also been observed. Aims: The aim of the study was to determine the predominant pattern of lip prints in males and females belonging to Central India; to determine the existence of heredity pattern. Materials and Methods: Five hundred lip prints were collected from 200 males and 300 females. Twenty-five families, each family comprising of father, mother, and offspring were also examined. Y. Tsuchihashi’s classification was used for determining the different types of prints in each sex and the families. The frequency of occurrence in percentage was calculated. Results: Chi-square test was used for intergroup comparison followed by Marascuilo for intragroup comparison. Type I was the most predominant pattern observed in the study population. In females, Type I (P < 0.001) was significantly observed whereas in males Type II, III, and IV (P < 0.001) was seen. The frequency of occurrence of Type I and I pattern in females (50% and 27%, respectively) was significantly higher (P = 0.001, 0.001, respectively) compared to their frequency in males (13% and 6%, respectively). 80.77% of offspring showed resemblance to either of their parent. The resemblance of females to their mother and that of males to their father was found to be significant (P < 0.05). Conclusion: In Central India population, Type I pattern of lip prints is common in females and Type II, III, and IV in males. The lip print patterns of females resemble more to their mothers and that of males to their fathers.
