This study aimed to assess the lip prints of Indian twins and non-twin siblings to evaluate the existence of heredity in the lip prints of these individuals.
The study employed a blind, cross-sectional, quantitative approach with an inductive method and extensive direct observation. The sample consisted of 30 twins and 30 non-twin siblings, divided into three groups based on gender with 10 subjects in each subgroup. All participants were aged between 10 and 30 years and were instructed on the methods and techniques involved in the study.
The lip prints of participants were recorded using dark-colored lipstick, bond paper, cellophane tape, and a brush, and were examined for lip thickness measurement (in mm), classification of lip commissures, and assessment of groove patterns. The findings were then analyzed to determine the pattern of lip prints among twins and non-twin siblings.
Cheiloscopy, the forensic investigation technique based on lip trace identification, could benefit from this study's findings as it explores the existence of heredity in lip prints of Indian twins and non-twin siblings.
本研究旨在评估印度双胞胎和非双胞胎兄弟姐妹的唇纹，以评估这些个体唇纹中遗传因素的存在情况。
本研究采用盲法、横断面、定量研究方法，采用归纳法并进行广泛的直接观察。样本包括30对双胞胎和30对非双胞胎兄弟姐妹，根据性别分为三组，每个亚组有10名受试者。所有参与者年龄在10至30岁之间，并被告知研究中涉及的方法和技术。
使用深色口红、债券纸、玻璃纸胶带和刷子记录参与者的唇纹，并对唇厚度测量（以毫米为单位）、口角分类和沟纹模式评估进行检查。然后对结果进行分析，以确定双胞胎和非双胞胎兄弟姐妹之间唇纹的模式。
基于唇纹识别的法医调查技术——唇纹鉴定，可从本研究结果中受益，因为该研究探索了印度双胞胎和非双胞胎兄弟姐妹唇纹中遗传因素的存在情况。
