Lip print patterns varies among individuals hence this study aimed to identify the gender of an individual using lip print patterns and to  evaluate the predominant lip print pattern in males and females in Mysorean population. Lip prints of 395 subjects (195 male and 200  female) of Mysorean population origin were included in the study. Red coloured lipstick and cellophane tape was used to collect the lip  prints sample. The current study has found most frequent lip pattern type was Type I in 177 (44.8%) subjects followed by Type IVpattern in  115 (29.1%), Type II in 95 (24.1%) and Type III in 8 (2.0%) was least common pattern seen in overall subjects. In males, most frequent  patterns seen was (Type IV) in 66 (33.8%) subjects followed by (Type I) in 64 (32.8%), (Type II) in 58 (29.7%), (Type III) in 7 (3.6%)  subjects. In females most frequent patterns seen was (Type I) in 113 (56.6%) subjects followed by (Type IV) in 49 (24.5%), (Type II) in 37  (18.5%) and ( Type III) in 1(0.5% ). The study group comprised of 195 males and 200 females 73 were correctly determined as males and  150 were correctly determined as females. Type I is the most predominant pattern found in Mysorean population and lip prints are reliable  tool for recognition of the gender of an individual.
