Background: It is well established that dermatoglyphics are genetically determined. But, to date, few studies have given attention to the inheritance pattern of dermatoglyphics. Furthermore, despite the existence of different advanced statistical packages, none of these previous studies implemented a model-fitting technique to reveal the mode of inheritance. Thus, the genetic nature of dermatoglyphics is still not clear. Aim: In the present communication, an attempt has been made to provide… 

Genetic Determinants of 22 Quantitative Dermatoglyphic Traits in the Chuvashian Population of Russia: Complex Segregation Analysis

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 pal- mar a-b ridge counts.

Genetics of Dermatoglyphic Asymmetry in Vaidyas of West Bengal, India

The present results support the hypothesis that both types of asymmetry have a genetic basis and are influenced by the intrauterine environment.

Complex segregation analysis of quantitative dermatoglyphic traits in five Indian populations

Major gene involvement in finger dermatoglyphics according to Mendelian models is confirmed and the nature of transmission and trait variance strongly supports the existence of a common nature of dermatoglyPHic trait inheritance in populations, irrespective of ethnic and geographic area.

Mode of inheritance of dermatoglyphic pattern intensity index on fingers in five Indian populations: A comparative study between individual trait and its factor

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 traits PII and its factor (factor 1) with respect to mode of inheritance.

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.

Anthropological significance of dermatoglyphic trait variation: an intra-Tunisian population analysis.

The intra-Tunisian population analysis shows that Tunisians living in the North and the expanded East Centre of Tunisia are genetically very close, while Tunisians from the extreme East Center and the South of Tunis are relatively less close to them.

FINGER AND PALMAR DERMATOGLYPHICS IN MUZEINA BEDOUIN FROM SOUTH SINAI: A QUANTITATIVE STUDY

The results of palmar traits reveal homogeneity which also presents a common picture obtained in the earlier studies, perhaps due to the possible role of environmental (prenatal) factors in the realization of dermatoglyphics between finger and palm.

Inheritance of six anthropometric traits in Vaidyas of West Bengal, India

An attempt to approach the problem of the inheritance of anthropometric traits through advanced statistical applications indicated that additive genes are not the only contributing factor; the effect of environment is considerable and that of dominant genes not negligible.

A Comparison of Palmar Dermatoglyphics in Two Ethnic Indian Populations of North Bengal, India *

The present investigation further highlights the racial affinity, sex, and bilateral differences among Rajbanshi individuals using dermatoglyphic palmar variables, which appear to be limited only to ethnic identification, not personal identification.

Complex segregation analysis of body height, weight and BMI in pedigree data from Middle Dalmatia, Croatia.

Evidence is presented that supports the hypothesis that a significant part of the variation of each one of the basic morphological traits can be attributed to the effect of a putative large-effect gene in the island populations of Middle Dalmatia, Croatia.

Data suggest inbreeding effects for SBP, with a pattern of smaller variances due to multifactorial sources (i.e., polygenic and/or cultural) in the sample which included consanguineous families.

Major gene control of human body height, weight and BMI in five ethnically different populations

Analysis in 5 populations showed that except for Mexican sample, the proportion of variance attributable to major gene effect ranged between 37 and 53% for body weight and height, and showed that strong assortive mating in body height, as estimated by correlation between putative major gene genotypes in spouses, was found in four populations, not including Mexican pedigrees.
