The analysis of whorls on specific fingertips with respect to sex, bilateral asymmetry, and genetic relationship

Abstract

In a sample of 539 Polish families, 1000 individuals (515 males and 485 females) were analysed to determine the distribution of whorl patterns on specific fingertips, to compare their frequencies in males and females, and to determine whether asymmetry of these dermatoglyphic pattern elements is genetically controlled. Whorls occur most commonly on digit VI on both hands and in both sexes. The difference between males and females for mean values of occurrence is not significant. Using the bimanual difference between hands (right minus left), the digital asymmetry was determined, and correlations with asymmetrical occurrence of whorls was made between parents and children, and between sibs, in all combinations. In each case, there was a positive correlation pairs of relatives, demonstrating a genetic component in whorl determination and their asymmetrical occurrence.

“…On the other hand, there was no evi dence for genetic determination of asymme try. This finding is consistent with that noted by several investigators, both for der mal ridge counts [58,59] and other morpho logical structures [60,61], although Bener and Erk [62] have reported a genetic com ponent in the asymmetry of the whorl dermatoglyphic pattern type.…”

Inbreeding Effects on Bilateral Asymmetry of Dermatoglyphic Patterns

“…However, the results of these studies are not consistent between sexes, between fingers, between different types of relatives, and between the two types of asymmetry. Again, the suggestion of a small heritability of directional asymmetry of pattern elements (triradii) of loops and whorls (Bener 1979;Bener and Erk 1979) remains incomplete due to significant negative correlations between sibs for some fingers and absence of significant father-offspring correlations for loop elements. Pons (1961) also obtained small sibpair and mother-offspring correla-tions for main line index on palms, but correlations between monozygotic twins and between fathers and offspring are not significant.…”

The Study of Dermatoglyphic in Simian Crease Group (The Human Masukake-Gata) at Minangkabau Ethnic, West Sumatra, Indonesia

“…The highest frequency of arch patterns were also found on the same finger in both groups (the second finger/index finger). According to Bener & Erk 15 , in general the type of whorl patterns often appear on the fingertips I and IV, then the type of loop patterns often appear on the fingertips III and V, the type of arch patterns often appear on the fingertips II at right and left hand in both men and women were influenced by genetic factors. The highest frequency of radial loop patterns were found on the same finger in normal group and simian crease group (index finger/the second finger).…”
