TL;DR: Examination of the association between hand clasping and arm folding in the Basques shows a strong correlation between the right type of one and the left type of the other.
Abstract: Hand clasping and arm folding have been analysed in 286 males and 455 females of the Basques. The results are compared with those from other Spanish populations. Examination of the association between hand clasping and arm folding shows a strong correlation between the right type of one and the left type of the other.

TL;DR: The a-b palmar interdigital ridge count was analyzed in a sample of 841 males and 911 females of Basque origin and found no significant sexual dimorphism.
Abstract: The a-b palmar interdigital ridge count was analyzed in a sample of 841 males and 911 females of Basque origin. Bimanual differences were not found, against that a significant sexual dimorphism. The mean ridge count value is in the lower lange of the variability among White populations.

TL;DR: This work proposes the building of two new subclasses of spiral monocentric whorls to replace the traditional ones in order to conserve the bilateral identification of these pattern types.
Abstract: 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 the building of two new subclasses of spiral monocentric whorls to replace the traditional ones in order to conserve the bilateral identification of these pattern types.

TL;DR: The importance of clarifying pattern types according to their orientation is reaffirmed, which is of general use in the case of loops but less easily applied to whorls.
Abstract: 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.

TL;DR: The results of the chi 2 test for pattern types in males and females show statistically significant differences between the Basques and other Spanish populations, with the exception of the males from El Bierzo.
Abstract: 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 (chi 2 contingency test and Student's t-test) and multivariate (principal components analyses) statistical methods. Bilateral distribution asymmetry and sexual dimorphism were observed in the Basque sample. The results of the chi 2 test for pattern types in males and females show statistically significant differences between the Basques and other Spanish populations, with the exception of the males from El Bierzo. Comparing populations with regard to the Pattern Intensity Index, the differences observed are much lower; therefore, this confirms what other authors have suggested regarding the limited usefulness of indexes in populational comparisons. In the Caucasian variation range of pattern types, Basques are located in the high part with regard to arches, in the low part with regard to whorls and radial loops, and in an intermediate part in relation to ulnar loops and overall pattern intensity. Results of the multivariate comparisons show which populations are more or less distant from the Basque population and which variables are significant in contributing to these population relationships.

TL;DR: The results suggest that the a-b count in males seems to be more influenced by environmental factors than the other counts, and for females, the three interdigital counts seem to have a strong genetic component influencing their phenotypic expression.
Abstract: 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.

TL;DR: Familial data suggest that hand-clasping may be under genetic control: although the data do not fit any straightforward recessive or dominant Mendelian model, they are compatible with the type of model invoking fluctuating asymmetry which has been used to explain the inheritance of handedness and arm-folding.
Abstract: Hand-clasping refers to the preferential tendency for individuals to clasp the hands together. This paper reviews the previous literature on family data and twins, and reports new data. In this study about 55% of the population are left-hand-claspers, 44% are right-hand-claspers, and the remaining 1% report that they have no preference or are indifferent. Familial data suggest that hand-clasping may be under genetic control: although the data do not fit any straightforward recessive or dominant Mendelian model, they are compatible with the type of model invoking fluctuating asymmetry which has been used to explain the inheritance of handedness and arm-folding. It is possible that hand-clasping, as for example arm-folding, may be an idiosyncrasy due to or influenced by physical bilateral differences in the hands. All data together are suggestive of a genetic basis, although environmental influences are also evident.

TL;DR: In the psychotics with uppermost right positions in both tests, good prognostic clinical features were most pronounced and are interpreted on the basis of possible relationships between hemispheric asymmetries and lateral preferences.
