To investigate the frequency and uniqueness of different lip print patterns, fingerprint patterns in relation to gender and ABO Rh blood groups among a semi-urban population of Sriganganagar, Rajasthan.
The study was conducted on 1200 healthy volunteers aged 18-30 years. The cheiloscopic and dermatographic data of each subject were obtained and were analysed according to the Suzuki and Tsuchihashi and Henry systems of classification, respectively. Two forensic experts analyzed the patterns independently. The ABO Rh blood group was also recorded for each subject. The Chi square statistical analysis was done and tests were considered significant when p value <0.001 and Cohen kappa test was applied to analyze inter-observer reliability.
The B+ blood group was noted as most common in both genders while least common were A- among males and AB- in females. Type II lip pattern was most predominant while the least common was Type I' in males and Type I' and Type V in females. The UL fingerprint pattern was the most common, while RL was least noted in both genders. All the fingerprint patterns showed correlation with different lip print patterns. A correlation was found between different blood groups and lip print patterns except Type I (vertical) lip pattern. A positive correlation was observed between all the blood groups and fingerprint patterns, except for RL pattern.
There is an association between lip print patterns, fingerprint patterns and ABO blood groups in both the genders. Thus, correlating the uniqueness of these physical evidences sometimes helps the forensic team members in accurate personal identification or it can at least narrow the search for an individual where there are no possible data referring to the identity of the subject.
调查拉贾斯坦邦斯利甘加纳格尔半城市人口中不同唇纹模式、指纹模式与性别及ABO Rh血型之间的出现频率和独特性。
对1200名年龄在18至30岁的健康志愿者进行研究。获取每位受试者的唇纹和指纹数据，并分别根据铃木和土桥分类系统以及亨利分类系统进行分析。两名法医专家独立分析这些模式。同时记录每位受试者的ABO Rh血型。进行卡方统计分析，当p值<0.001时，检验被认为具有显著性，并应用科恩kappa检验分析观察者间的可靠性。
B+血型在两性中均最为常见，而男性中最少见的是A-，女性中最少见的是AB-。II型唇纹最为主要，而男性中最少见的是I'型，女性中最少见的是I'型和V型。双手上指纹模式中，左手环指指纹模式最为常见，而右手环指指纹模式在两性中均最少见。所有指纹模式均与不同唇纹模式存在相关性。除I（垂直）型唇纹外，不同血型与唇纹模式之间存在相关性。除右手环指指纹模式外，所有血型与指纹模式之间均观察到正相关。
两性的唇纹模式、指纹模式与ABO血型之间存在关联。因此，关联这些物证的独特性有时有助于法医团队成员进行准确的个人身份识别，或者至少在没有可能的身份数据时缩小对个体的搜索范围。
