The genetic and environmental contributions to determine digital dermatoglyphic traits were investigated by using female dizygotic and monozygotic twin pairs to estimate heritability indexes (h2). The evaluated sample was composed by 20 monozygotic twin pairs and 13 dizygotic twin pairs. A significant heritability (h2 = 0.65 to 0.96) was observed for 12 dermatoglyphic characteristics (delta indexes and ridge counts for right hand, left hand and both hands, and ridge counts for most individual… 

Three Patterns of Inheritance of Quantitative Dermatoglyphic Traits: Kosovo Albanian Twin Study

Investigating the genetic and environmental contribution in determining quantitative dermatoglyphic traits in 32 monozygotic and 35 dizygotic same-sex twins from the Albanian population of Kosovo indicates that additive genetic component strongly contributes to individual differences in finger ridge counts, and weakly on the formation of the palmar ridge counts.

Association between fingerprint patterns and myopia

Analysis of fingerprint patterns has showed significantly altered dermatoglyphic configuration of arch patterns in myopic group, which might be suggestive of developmental perturbances in embryogenesis of genetically vulnerable individuals prone to development of myopia.

Distribution of the minutiae in palmprints: Topological and sexual variability

A study was conducted to assess total, bimanual, and sexual density per morphological regions and per counting areas on 120 palmprints obtained from 30 male and 30 female individuals of Spanish nationality, showing a topological variability in the distribution of the density of minutiae.

Fingerprint pattern similarity: a family-based study using novel classification

Morphological evidence from this study suggests that fingerprints are more genetically determined than environmentally influenced; however, the pattern in which they are inherited seemed closer to co-recessivity with complex expressivity.

The frequency of fingerprint patterns separated by ethnicity and sex in a general population from Sydney, Australia

ABSTRACT A total of 514 individuals from the Sydney area volunteered their fingerprint scans for analysis. The prints were classified using the eight main patterns of the National Crime Information

Hot on the Trail of Genes that Shape Our Fingerprints.

Association of ADAMTS 9-AS 2 with the formation of whorls on digits indicates that long noncoding RNA ( lncRNA )-directed epigenetic regulation

Ho et al. point out some key variants that may be responsible for some of the concentric patterns that are observed in digital skin and propose that one highly associated gene, ADAMTS9-AS2, has a role in epigenetic regulation, a role that might be important in early-stage digit development.

The Study of Three-Dimensional Fingerprint Recognition in Cultural Heritage

The aim is to outline the opportunities and challenges of digital fingerprint recognition in answering a range of questions in cultural heritage research and analyze the works conducted on ancient fingerprints from potteries and ceramic/fired clay sculptures to suggest that the study of ancient fingerprints can be further investigated and open new avenues of research.



High heritability of fingertip arch patterns in twin‐pairs

With such high heritability, the search for specific genes influencing the occurrence of fingertip arch patterns is justified and the analysis of pedigrees with this trait segregating is justified.

Maternal effects on fingertip dermatoglyphics.

The trend indicated that the observed thumb changes may be reflected in the TRC as well, and little finger pattern type and ulnar counts showed less variability in families of female MZ twins, but the interpretation is complicated by the concomitant differences in mean squares within-sibships for these little finger variables.

Mode of inheritance of finger dermatoglyphic traits among Vaidyas of West Bengal, India

The present report supports the evidence of the existence of a major gene on these dermatoglyphic traits and the transmission of this effect is consistent with Mendelian expectation.

Maternal effects in dermatoglyphics: similarities from twin studies among palmar, plantar, and fingertip variables.

The methodology is extended to palmar and plantar dermatoglyphic variables and the ratio MBP/MBM is used to test for maternal influences.

Comparisons of dermatoglyphic patterns in monochorionic and dichorionic monozygotic twins.

The data presented here indicate that different influences affect dermatoglyphic pattern development in MC-MZ and DC-Z twins, and this may provide a mechanism for retrospectively diagnosing placental type of MZ twins.

Analysis of the covariance structure of digital ridge counts in the offspring of monozygotic twins.

A confirmatory factor analysis of dermal ridge counts on the individual fingers of 509 offspring of 107 monozygotic twin pairs is conducted using Jöreskog's Lisrel IV computer program.

Linkage Analysis of a Model Quantitative Trait in Humans: Finger Ridge Count Shows Significant Multivariate Linkage to 5q14.1

The combination of univariate and multivariate results was more informative than simple univariate analyses alone and the simple pleiotropic model underlying the absolute ridge count was not sufficient to characterize the interrelationships between the ridge counts of individual fingers.

Within-pair differences in a-b ridge count asymmetry in monozygotic twins: evidence for a placental proximity effect.

Asymmetry of a-b ridge count, a dermatoglyphic trait in the second interdigital (ID II) palmar area was studied in 314 identical (MZ) twin-pairs of known placental type and showed consistent with a placental proximity effect like that known for the variability in birth weight in twins.
