Cytogenetics of autosomal fragile sites: A Basque population study
Population cytogenetic data on autosomal fragile sites show differences among different ethnic groups. The Basques are an ancient population; their origin is not exactly known and many studies using several traits have shown peculiarities in the Basques. This is the first study about the incidence of autosomal fragile sites in a healthy Basque sample. The results show interindividual variability, no sex differences at a global level, but differen…
Fluctuating dermatoglyphic asymmetry: Genetic and prenatal influences
Genetic and environmental prenatal factors influencing the fluctuating asymmetry of the a-b interdigital ridge count are examined. From the results obtained we can conclude that fluctuating asymmetry of the a-b interdigital ridge count is poorly influenced by genetic factors. We suggest that fluctuating asymmetry of dermatoglyphics provides a good measure of developmental stability in humans, especially for males. The results also indicate that r…
Twin study of digital dermatoglyphic traits: Investigation of heritability
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 rig…
Characterization of digital dermatoglyphic features in Salazar Valley: Comparison with other Basque valleys
Digital dermatoglyphics of a sample from the Basque Valley of Salazar, situated in the West of the Pyrenees, were analysed. The results showed bimanual differences in both sexes, and also sexual differences for both hands. The comparative study with other Basque valleys showed that, in spite of their supposed common origin, the geographic barriers and the isolation have generated a genetic/dermatoglyphic and linguistic differentiation
Finger ridge count in Basque populations: Univariate and multivariate comparison with other Spanish populations
We have analysed finger ridge counts in the indigenous Spanish Basque population (841 males and 911 females). Bimanual and sexual variation have proved to be statistically significant. The results in the Basque population were compared with those of other Spanish populations. In the univariate comparison statistically significant differences appear. The means found in the Basque population are the lowest. Our population is situated on the lower p…
Correspondence analysis of digital pattern types in Basque valleys
Fingers pattern types of a sample of 834 unrelated individuals (353 males and 481 females) from the Biscaian Basque valleys of Uribe, Gernika, Markina, Arratia and Durango were subjected to correspondence analysis. The results show that there are different local subpopulations with regard to these dermatoglyphic traits. The importance of whorls in the separation of these populations is observed. Isolation may have been the factor differentiating …
Subclassification of spiral monocentric whorls
Despite all the papers on the classification of dermatoglyphic features, there is no definitive in sight yet. With this work we intend to contribute to adapt the subclassification of spiral monocentric whorls to their biologic nature. The results in this work show that clockwise whorls on the right hand match counter-clockwise ones on the left, and counter-clockwise spirals on the right are joined together with clockwise on the left. We propose t…
Digital dermatoglyphics in the Basque population: Univariate and multivariate comparison with other Spanish populations
We have analyzed dermatoglyphic finger patterns in a Spanish Basque population (841 males and 911 females). Bimanual and sexual comparisons have been carried out by means of contingency analysis. The results in the Basque population are compared with those of other Spanish populations, based on univariate (χ 2 contingency test and Student's t‐test) and multivariate (principal components analyses) statistical methods. Bilateral distribution asymme…
Parallelism between the frequencies of differently oriented whorls and other pattern types in Basque population
In a sample from the Biscaian Basque population, we studied the incidence of pattern types in fingers and the parallelism between the frequencies for the orientations of whorls (Wr, Ws, Wu) and the other pattern types (Lr, A, Lu). We reaffirm the importance of clarifying pattern types according to their orientation, which is of general use in the case of loops but less easily applied to whorls
