“…Furthermore in previous study by Arrieta and Losta (1988) it was shown that the two sides of a finger correspond to different developmental instructions, although they are in the same finger. This finding agrees with the previous studies of Roberts and Coope (1975), Jantz and Owsley (19771, Jantz and Hawkinson (1979), Meier (1981), and Lin et al (1983).…”

Digital patterns of a sample of monozygotic and dizygotic twins were analyzed to obtain heritability values for the four basic types of patterns: arch, tented arch, loops, and whorls. Loops have been separated according to their orientation radial or ulnar. To carry out this study, we used the Holzinger and Clark indices. The results show highest concordances for monozygotic twins except for ulnar loops of the left hand and radial ones of the right hand. Different values of heritability were found for the right and left hands, with finger I having the highest values.

“…The results obtained by several authors support the idea that, although both sides (radial and ulnar, form a part of the same finger, they follow different development instructions (ROBERTS and COOPE 1975;JANTZ and OWSLEY 1977;JANTZ and HAWKINSON 1979;MEIER 1981;LIN et al 1983;and ARRIETA and LOSTAO 1988). These results reinforce the importance of using the radial and ulnar counts as separate variables.…”

Fluctuating asymmetry in quantitative dermatoglyphic traits: twins and singletons

et al. 2008

Fluctuating asymmetry for the digital quantitiative value was analyzed in a sample of twins (mono and dizygotic) and singletons. The aim was to check if the influence of twinning on the development is expressed in a higher fluctuating asymmetry in twins than in singletons. The results have shown that significant differences exist among the three groups studied, and these differences are fundamentally expressed when the radial and ulnar counts are considered separately.

“…Nowadays, for fingerprints, there is a general tendency to consider the genetic and environmentalmaternal factors jointly in a coherent genotype-environmental model ( SIERVOGEL et al 1978;MEIER 1980;LIN et al 1983;ARRIETA et al 1991). According to MEIER (1980), during limb and hand development, specific fields and subfields are organized along the growth axes, which direct and control tissue formation and blood and nerve supply.…”

Effects of genetic and environmental factors on the a-b, b-c and c-d interdigital ridge counts

et al. 2008

A study of 100 MZ (55 female and 45 male) and 97 DZ (50 male and 47 female) same-sexed twin pairs was carried out to analyse the genetic component of the variance of the a-b, b-c and c-d interdigital ridge counts by means of the Christian method. Especially for the a-b interdigital ridge count, we found it important to analyse both sexes separately. Our results suggest that the a-b count in males seems to be more influenced by environmental factors than the other counts. For females, the three interdigital counts seem to have a strong genetic component influencing their phenotypic expression. Factor analysis with VARIMAX rotation showed each interdigital ridge count to be genetically independent.
