TLDR
The nature of variation of these components appears with a good similarity between sexes, which suggests their common biological validity of the underlying component structures of the finger and palmar dermatoglyphic characters.Abstract:
With the aim of determining sexual dimorphism in the component structures among the Chuvashian population of Russia, finger and palmar dermatoglyphics of 547 individuals (293 males, 254 females) were analyzed. The sex differences in two categories of dermatoglyphic traits (22 quantitative traits and 38 asymmetry and diversity traits) are reflected differently and contradictory with other ethnic groups. However, a common feature of the factor 1 »digital pattern size factor« (finger ridge counts from the first category of traits) indicate its degree of universality when compared with other populations, which suggests that the variability of finger ridge counts is determined by the same genes that control the pattern types. The factors »intra-individual finger diversity factor«, and »bi-lateral asymmetry factor« extracted from the second category of dermatoglyphic traits are also similar in both sexes. However, these components are hardly described in the literature. The nature of variation of these components (from two categories of dermatoglyphic traits) appears with a good similarity between sexes, which suggests their common biological validity of the underlying component structures of the finger and palmar dermatoglyphic characters.read more

Sex differences in fingerprint ridge density in the Mataco-Mataguayo population
TL;DR: Variations in RD in the Amerindian population based on sex, age, and topology were confirmed in this work, and it is postulated that these variations are due to developmental differences among individuals and populations.

A study of sex differences in fingerprint ridge density in a North Indian young adult population.
TL;DR: The present study suggests that the fingerprint ridge density can be a relevant and useful morphological parameter in distinguishing sex of a latent fingerprint of unknown origin from the scene of crime.

Sexual dimorphism in finger ridge breadth measurements: a tool for sex estimation from fingerprints.
TL;DR: This study uses a novel method for measuring sexual dimorphism in finger ridge breadths to evaluate its utility as a sex estimation method from an unknown fingerprint and demonstrates statistically significant differences in ridge breadth between males and females.

Sex differences in fingerprint ridge density in a Turkish young adult population: A sample of Baskent University
TL;DR: In this article, the ridge density was found to be significantly higher in women in every region studied and in all fingers when compared to men, and the fingerprint ridge density in the ulnar and radial areas of the fingerprints was significantly greater than the lower area.

TL;DR: This book is indispensable for the dermatologist and for any pathologist dealing with dermatological material, and the provision of reasonably full and up-to-date lists of references following each chapter is the greatest merits.

TL;DR: This paperback volume is an unabridged and corrected republication of the pioneer work on dermatoglyphics first published in 1943 and is pleased to see it is again available.
