Objective of this study is to explore the nature of sex differences between two different sets of dermatoglyphic traits based on principal components in the Turkmenian population. Two categories of dermatoglyphic traits--22 usually studied quantitative traits and 42 variables of diversity and asymmetry were analysed among 745 individuals (309 males and 436 females). The three principal components are very prominent in both sexes--"digital pattern size factor" indicates the degree of universality, as found in earlier studies among different ethnic populations; "intra individual diversity factor" and "bilateral asymmetry factor" are also similar with the earlier studies, which suggest the genetic factor has more influence on these variables than environmental factors. These results strongly indicate that there is a common biological validity exists of the underlying principal component structures between two different sets of dermatoglyphic characters and thus dermatoglyphic factors between two groups of variables can be used for sex-discrimination in different populations.
本研究的目的是基于土库曼人群的主成分，探讨两组不同皮纹特征之间性别差异的本质。在745名个体（309名男性和436名女性）中分析了两类皮纹特征——22个通常研究的数量性状以及42个多样性和不对称性变量。三个主成分在两性中都非常突出——“指嵴纹大小因子”表明普遍性程度，这与早期在不同种族人群中的研究结果一致；“个体内多样性因子”和“双侧不对称因子”也与早期研究相似，这表明遗传因素对这些变量的影响大于环境因素。这些结果有力地表明，两组不同皮纹特征之间潜在的主成分结构存在共同的生物学有效性，因此两组变量之间的皮纹因子可用于不同人群的性别鉴别。
