The fingernail ridge patterns of a pair of identical twins were compared to each other, their parents, and an unrelated subject. The patterns of the twins' nails showed regions of strong similarity but were distinguishable from one another. Fewer similarities were found when comparing the nails to those of the parents and the unrelated control. The twins were shown to be monozygotic by means of DNA profiling. This therefore represents the first demonstration of unique fingernail ridge patterns in subjects shown conclusively to be identical twins. When the fingernail ridge patterns were examined with a scanning electron microscope, the backscattered electron (BEI) images were found to have superior contrast when compared to the secondary electron (SEI) images.
对一对同卵双胞胎的指甲嵴纹图案进行了相互比较，并与他们的父母以及一名无关个体进行了比较。双胞胎指甲的图案显示出高度相似的区域，但彼此之间仍可区分。将指甲与父母及无关对照的指甲进行比较时，发现相似之处较少。通过DNA分析表明这对双胞胎是同卵双胞胎。因此，这首次证明了在经确凿证明为同卵双胞胎的个体中存在独特的指甲嵴纹图案。当用扫描电子显微镜检查指甲嵴纹图案时，发现背散射电子（BEI）图像与二次电子（SEI）图像相比具有更好的对比度。
