The presence of an arch pattern on at least one fingertip has previously been suggested as an autosomal dominant trait with reduced penetrance, although the examination of pedigrees with this trait segregating is also consistent with major gene or multifactorial inheritance. We utilized fingerprints in 2,484 twin‐pairs to estimate heritability for the presence of at least one fingertip arch pattern. The frequency of arches in the entire sample was 4.3% (2,175/50,850), 5.5% in females and 3.2…

Digital Dermatoglyphic Heritability Differences as Evidenced by a Female Twin Study

TLDR
The heritability indexes varied in up to 8 times between different fingers and its association to ridge counts and pattern frequency was very variable between hands, evidencing that the use of dermatoglyphic traits from individual fingers as indicators of genetic influences to other human traits should consider this variability.

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

TLDR
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

TLDR
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.

FINGER PAPILLARY TRAITS IN BULGARIAN FEMALE BREAST CANCER PATIENTS

TLDR
These statistically significant differences between breast cancer patients and healthy females in terms of the mean values of fingerprint papillary traits of all the five homologous fingers could contribute to the enrichment of the screening and prognostic dermatoglyphic armamentarium in the field of breast cancer.

Gender identification from thumbprint ridge thickness among Hausa population of Nigeria using likelihood ratio and posterior probability density

TLDR
In conclusion, considering equal probability for each sex, likelihood ratio reveals the applicability of ridge thickness in sex inference among Hausa population.

Distribution of the minutiae in palmprints: Topological and sexual variability

TLDR
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.

Application of likelihood ratio and posterior probability density in sex estimation from level two fingerprint features among Hausa ethnic group

BackgroundIn forensic sciences, the nature and variability of configurations of epidermal ridge minutiae has practically been explored in the evaluation and comparison of fingerprints, including

The inheritance of digital dermatoglyphic patterns in 54 American Caucasian families.

TLDR
The Louisianians showed evidence for single gene effects similar to that of the Israelis, and the findings support the concept of an incompletely penetrant dominant gene.

Genetic analysis of dermatoglyphic patterns in twins.

TLDR
Patterning was more genetically controlled in the hand than in the foot and the hallucal area had the most significant genetic component of the foot while the patterns in the thumb had nonsignificant components of genetic variance.

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

TLDR
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.

X inactivation as a source of behavioural differences in monozygotic female twins.

TLDR
Interestingly, dizygotic twins showed the reverse pattern of correlations for similar variables, which is consistent with the X inactivation hypothesis and suggests the presence of quantitative trait loci on the X chromosome.

Evaluation of a dermatoglyphic index to detect placental type variation in MZ twins

TLDR
An association of the placental type dermatoglyphic score with another variable in a group of MZ twins without any placentation information provides support for continuing to investigate prenatal effects on the associated variable.

Modelling fingerprint pattern inheritance.

TLDR
The authors compare some genetic triallelic models for finger-print pattern inheritance built according to the Galton classification with reliable data, collected and classified by Alciati and Folin, of the Institute of Anthropology of the University of Padua.

Replication of asymmetry ofa−b ridge count and behavioral discordance in monozygotic twins

TLDR
The results offer new evidence for the hypothesis that an asymmetrica−b ridge count may identify individuals who are poorly buffered from developmental noise, but analyses of symmetric and asymmetricb ridge counts in nontwin subjects are required to extend and test the hypothesis further.

Linkage analysis and the inheritance of arches in a Habbanite isolate.

TLDR
A pedigree and linkage analysis was performed on a corrected version of the Habbanite pedigree 2 and confirmed the proposed dominant major gene inheritance of this trait with almost complete penetrance and suggests linkage with the haptoglobin locus with evidence against linkage with Pl and Rhesus.

Comparisons of dermatoglyphic patterns in monochorionic and dichorionic monozygotic twins.

TLDR
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.

Sequential developmental components of digital dermatoglyphics.

TLDR
A modified developmental field theory was proposed which placed the digital fields in a sequential arrangement based upon the elevation of volar pads at the timing of their regression, and the little finger was postulated to undergo primary ridge formation first over apical pads having the lowest elevation, the middle digits followed and the thumb was last to complete ridge formation on the highest and longest sustained pads.
