Abstract

Using a special method, the dermatoglyphics of the plantar interdigital areas of 86 monozygotic and 76 dizygotic Polish twin pairs were obtained. The frequencies of different types of zygodactylous triradii were estimated using a recently published new scheme of classification. The second, third, and fourth interdigital areas were grouped together. The findings indicate a high heritability which suggest that zygodactylous triradii might be used as a valuable genetic marker.

摘要

采用一种特殊方法,获取了86对波兰同卵双胞胎和76对异卵双胞胎足底指间区域的皮纹。使用最近公布的新分类方案估计了不同类型对趾三叉点的频率。将第二、第三和第四指间区域归为一组。研究结果表明遗传力较高,这表明对趾三叉点可能用作一种有价值的遗传标记。
