“…support this field theory. The three factors of the present study are exactly the same as our previous findings [5] of five Indian populations, which suggest that the internal structure of the dermatoglyphic variables represented by the factors are common irrespective of different ethnic/ geographical populations.…”

“…There is no striking difference in the correlation values of the three kinds of parent-child combinations, but these correlations are positive and significant, with few exceptions. These results suggest the strong involvement of family factors (presumably genetics) in determining the variation of dermatoglyphic traits, which was supported by several earlier studies on family resemblance [4,5,7,9,33,53,[56][57][58]. Similar results also appear from family correlations based on factors ( Table 3).…”

“…Roberts [10] reported Factor 1 for finger patterns in the English sample; Das Chaudhuri and Chopra [53], in comparing 100 Andhra families, also reported factors 1, 2, and 3, as we also observed in the present study. However, a general factor (Factor 1) was missing in the analysis of Knussman [5] and in Jantz and Owsley's [3] study; perhaps this discrepancy was due to the different sets of variables included in the analysis. The present findings support earlier suggestions [5,[51][52][53] that finger and palmar variables are controlled by independent factors because in palmar variables a general factor has not been identified.…”

The present findings support earlier suggestions [5,[51][52][53] that finger and palmar variables are controlled by independent factors because in palmar variables a general factor has not been identified. Palmar variables are composed of different factors, unlike finger ridge counts (Factor 1), and these are for main line termination (Factor 2) and for the a-b ridge count (Factor 3).…”

“…Several researchers who have used traditional methods of genetic analysis concluded that different genes are probably responsible for dermatoglyphic traits [2][3][4]. However, the conclusions from various studies are still contradictory [5][6][7][8][9][10][11][12][13][14][15][16]. All the earlier studies were based only on the statistical application of familial correlation or regression between relatives; however, these methods are insufficient to detect the mode of inheritance of a trait.…”

Abstract:Background: Dermatoglyphics is widely used as a genetically determined trait in Anthropology. However, little is known about their pattern of inheritance due to lack of advanced statistical genetic model-fitting techniques despite the existence of advanced statistical packages.Objectives: The aim of the present study is to determine the mode of inheritance of dermatoglyphic traits through complex segregation analysis. Subjects and Methods:Finger and palmar prints of 325 individuals belonging to 104 families from the Chuvashian population of Russia were used for principal component analysis, familial correlation, and segregation analysis (package MAN-5). Results:The results suggest a common internal structure of three factors when compared with other populations. (b) Significant familial correlations (except spouse) indicate the involvement of familial components to the variation of dermatoglyphic traits. (c) Segregation analysis reveals the transmission of genetic effects in the families, which follows the Mendelian model and confirm major gene effect on factors 1 and 2, whereas there is no evidence of major gene effect or an environmental effect on factor 3. Conclusion:Major gene involvement with Mendelian expectation regarding finger dermatoglyphics is confirmed for all analyzed traits. However there is no evidence of significant support for major gene effect or environmental effect on palmar a-b ridge counts.

Our previous study (Karmakar et al. 2005 Ann. Hum. Biol. 32:445-468) was on 500 pedigrees of five different populations, with factor 1 comprising quantitative finger dermatoglyphics (including pattern intensity index, PII) and factor 1 controlled by major genes. The present results of a complex segregation analysis of the individual trait PII of the same five populations were compared with previous results to ascertain the extent of variation between individual trait PII and its factor (factor 1) with respect to mode of inheritance. The comparative findings are very similar in five populations, irrespective of different ethnic groups. This result suggests that the variability of their biological relevance is influenced by the same genetic component, thus representing a similar mode of inheritance with major gene involvement in all populations.

High heritability of fingertip arch patterns in twin‐pairs

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% in males. There were 267 twin-pairs concordant for the presence of an arch on any finger. Structural equation modeling was performed to contingency table data for five groups (MZ male, MZ female, DZ male, DZ female, and unlike-sexed DZ). The best fitting model, which allowed for the prevalence of arches to differ between males and females, had a heritability of 91%. There was some evidence for small dominant genetic effects in females and shared environmental effects in males, although both were not significant. With such high heritability, the search for specific genes influencing the occurrence of fingertip arch patterns is justified.
