Abstract

The role of genetic factors in the determination of palmar dermatoglyphic patterns was investigated in a series of 49 MZ and 51 DZ twins, using Spearman's rank correlation and analysis of variance. Both methods indicated that the genetic effect in the distribution of patterns is highest in the interdigital III and lowest in the interdigital IV regions, the hypothenar and thenar showing intermediate values. As for interdigital II, no evaluation of genetic effects was possible using the nonparametric test, but the estimates of genetic variance indicate that inherited factors may play a relatively minor role in the pattern distribution of this area.

摘要

在一系列49对同卵双胞胎和51对异卵双胞胎中，使用斯皮尔曼等级相关和方差分析研究了遗传因素在掌部皮纹模式确定中的作用。两种方法均表明，模式分布中的遗传效应在指间Ⅲ区最高，在指间Ⅳ区最低，小鱼际和大鱼际显示中间值。至于指间Ⅱ区，使用非参数检验无法评估遗传效应，但遗传方差估计表明遗传因素在该区域的模式分布中可能起相对较小的作用。
