A collection of functions that contrast familial trait values between and across generations is proposed for studying transmission effects and other collateral influences in nuclear families. Two classes of structured exploratory data analysis (SEDA) statistics are derived from ratios of these functions. SEDA-functionals are the empirical cumulative distributions of the ratio of the two contras...

Background: Dermatoglyphics are the dermal ridge configurations on the digits, palms and soles. Dermatoglyphic polymorphism results from the co-operation of genetic and environmental factors. The Dermatoglyphic analysis is a valuable completion of initial diagnosis of some syndromes genetically determined. Our objective was to assess dermatoglyphics study results against standard chromosomal an...

Schizophrenia is hypothesized to be the result of an interaction between specific genetic factors and nonspecific insults during embryonic development. Dermatoglyphic abnormalities appear to mark these putative insults--providing information about the temporal sequence of aberrant developmental events as well as the organism's vulnerability to their adverse effects. In the present study, dermat...

In order to investigate the intergenerational change of dermatoglyphics, fingerprints of 400 individuals were collected from an endogamous caste Vaidyas of Barasat, West Bengal. Results were compared with the data of an earlier sample of Banerjee collected in 35 years before on the same community of the same area. As it is generally known that dermatoglyphics is selectively neutral, thus if no ...

autism is a neurodevelopmental disorder originating from early childhood; nevertheless, its diagnosis is in older ages. in addition to heredity, environmental factors are also of great significance in the etiology of the disease. dermatoglyphic patterns, albeit varied, remain stable for a lifetime and yield a large number of patterns upon examination. studies have shown a significant associatio...

Dermatoglyphic features, qualitative as well as quantitative, of finger and palm prints of 50 male I. C. D.-9 diagnosed catatonic schizophrenics and as many ethnically matched normal controls of the same sex were examined. Patients were found to differ from the control group in qualitative as well as quantitative features quite similar to the findings of the past three investigators. These diff...
