总细节点计数（TMC）和分叉指数（FI），即，在20对日本同卵双胞胎和异卵双胞胎的掌纹中检查了分叉在总细节中的比例。两种性状均无双侧差异。男性的TMC均值高于女性，但FI无性别差异。这两个性状在同卵双生子间均呈现较高的组内相关系数，表明这些性状受遗传控制。然而，没有观察到这两个性状之间的相关性。TMC和总掌趾间嵴计数之间存在轻微相关性。讨论了与分类标准有关的一些方法学问题。
The total minutia count (TMC) and fork index (FI), i.e., the proportion of forks in total minutiae, were examined in palm prints of 20 pairs each of monozygotic and dizygotic Japanese twins. No bilateral difference was found in either trait. The mean of the TMC was higher in males than in females, but the FI showed no sex difference. Both traits presented relatively high intraclass correlation coefficients between monozygotic twins, and genetic control of these traits is suggested. However, no correlation was observed between these two traits. A slight correlation was observed between the TMC and the total palmar interdigital ridge count. Some methodological problems concerned with classification criteria were discussed.
