In a sample of 500 persons, including 76 families with 133 children, 22 mono- and 17 dizygote twins, lip prints were prepared for the study of variability and genetical basis of ridge-pattern in the region of mucous membrane lips. Taking 4 classes of pattern with different ridge-branching as a basis we observed more frequently branched pattern at the upper lip and mainly simple pattern at the lower lip. About 30% of the lip-prints showed whirling figures--at the upper lip simple and median, at the lower lip double and paramedian. Investigations during several months showed stability against environmental factors. The results of twins, families and mother(father)-child combinations proved a genetical basis of lip-prints. Applications of cheiloscopy to genetical investigations are reported.
在一个由500人组成的样本中，包括76个有133个孩子的家庭、22对单卵双胞胎和17对双卵双胞胎，制备了唇纹用于研究粘膜唇部区域嵴纹模式的变异性和遗传基础。以4种具有不同嵴分支的模式类别为基础，我们观察到上唇的模式分支较多，而下唇主要是简单模式。约30%的唇纹显示有涡状纹——上唇为简单型和中间型，下唇为双涡状型和旁中间型。数月的研究表明唇纹对环境因素具有稳定性。双胞胎、家庭以及母子（父女）组合的研究结果证明了唇纹的遗传基础。报告了唇纹鉴定在遗传学研究中的应用。
