Analysis of variance was performed on 71 dermatoglyphic variables in 424 twin sets. Using a method of twin analysis estimates of genetic variance were obtained. 54 of the variables were quantitated using a scoring system with modifications of arch or no pattern = 0, loops = 1, whorl = 2. The results indicated a significant genetic influence in most pattern areas. Patterning was more genetically controlled in the hand than in the foot. The hallucal area had the most significant genetic component of the foot while the patterns in the thumb had nonsignificant components of genetic variance. The thumb deviated from patterning in the rest of the fingers and may be more closely related to big-toe patterning.
对424对双胞胎的71个皮纹变量进行了方差分析。采用双胞胎分析方法获得了遗传方差估计值。其中54个变量使用了一种评分系统进行量化，该系统将弓形或无图案设定为0分，箕形纹设定为1分，斗形纹设定为2分。结果表明，在大多数图案区域存在显著的遗传影响。手部图案比足部受遗传控制的程度更高。拇趾区域是足部遗传成分最显著的部位，而拇指的图案遗传方差成分不显著。拇指的图案与其他手指不同，可能与拇趾图案关系更为密切。
