Genetics of dermal ridges; the relation between total ridge-count and the variability of counts from finger to finger.
Several years ago the distributions of the ridge-counts on all ten fingers were given for a small sample of unrelated persons (Holt, 1949). A more detailed analysis has recently been made of the digital counts of a population sample of 1650 persons, 825 males and 825 females, and the results are given here. Included in the sample are the 100 males and 100 females whose counts were used previous...
متن کاملDevelopment of dermal ridges in the fetus.
This paper describes a new technique to inspect dermal ridges on the dermal surface instead of the epidermal surface. The dermal surface was exposed by chemical treatment and stained with toluidine blue. Dermal ridges are observable by the metachromatic effect of the reagent, which might suggest a close relationship between morphological characteristics and quantitative variations of biochemica...
متن کاملA Comparison of Slovakian Haban Populations Using Finger Ridge-Count Data
The present study has attempted to explore the relationship among three Slovakian Haban populations with other Central European populations using finger ridge-count data. A multivariate approach to the analysis of finger-ridge count data allows for the study of population relationships using R-matrix calculations. Historical and ethnographic evidence suggests that the Haban populations have rem...
متن کاملFinger ridge count correlations among four tribes of Andhra Pradesh, India.
The present paper reports the distribution of finger ridge count correlations among four tribal populations from Andhra Pradesh, India viz., Dulia, Kotia, Manne Dora and Manzai Mali, and examines the intra and inter population variation. Higher correlations are recorded in left hands compared to right hands, but they are not significant. The homologous fingers exhibit a stronger correlation. In...
متن کاملBrachydactyly and polydactyly with dermal ridge dissociation and ridge hypoplasia.
A child with brachymesophalangy and postaxial postminimal polydactyly was found also to have dermal ridge dissociation and ridge hypoplasia. She was the second child of unaffected, unrelated parents and was born after a normal pregnancy and delivery. No previous report of a similar combination has been traced.
