110 palms of MZ twins and 111 like-sexed pairs of DZ twins have been compared in respect of a concordance rate of the palmar, sole and finger-tip total pattern types. Dermatoglyphic patterns have been classified according to the topological method, and the distributions of the numbers of discordant pattern elements from homolateral, heterolateral and bilateral comparisons in MZ and DZ twins, respectively, are presented. The highest concordance occurs in homolateral comparisons in MZ twins and the lowest in heterolateral comparisons. Bilateral concordance is highest for sole and finger-patterns, while palmar patterns present a considerable degree of dermatoglyphic asymmetry. Palmar, sole and finger-tip patterns are also not alike in homolateral concordance rates within MZ and DZ twin pairs. The differences between MZ and DZ twins are much more pronounced for sole patterns than for palmar or finger-tip patterns, which is also reflected in the estimated H values. For soles, this may be in some way related to the considerable symmetry of patterns. The fact that some pattern elements are intercorrelated may also introduce a bias in estimates of heritability, based on twin material.
就掌纹、足底纹和指尖总纹型的一致率而言，对110对同卵双胞胎和111对同性异卵双胞胎进行了比较。皮纹模式已根据拓扑方法进行分类，并分别给出了同卵双胞胎和异卵双胞胎中来自同侧、异侧和双侧比较的不一致模式元素数量的分布情况。同卵双胞胎同侧比较的一致率最高，异侧比较的一致率最低。足底纹和指纹的双侧一致率最高，而掌纹存在相当程度的皮纹不对称。同卵双胞胎和异卵双胞胎对中，掌纹、足底纹和指尖纹的同侧一致率也不相同。同卵双胞胎和异卵双胞胎在足底纹上的差异比在掌纹或指尖纹上更为明显，这也反映在估计的H值中。对于足底纹，这可能在某种程度上与纹型的相当对称性有关。一些纹型元素相互关联这一事实也可能会在基于双胞胎材料的遗传力估计中引入偏差。
