A migration matrix model is used to investigate the behavior of neutral polygenic characters in subdivided populations. It is shown that gametic disequilibrium has a large effect on the variance among groups but none at all on its expectation. The variance of among-group variance is substantial and does not depend on the number of loci contributing to variance in the character. It is just as la...

Fluctuating asymmetry (FA) is defined as random deviations from bilateral symmetry of the body. Thus, its magnitude is often used to evaluate developmental homeostasis. In this study we evaluate the following hypotheses: 1) FA of dermatoglyphic traits has a significant genetic component; 2) prenatal maternal environment (PME) has a significant effect on the FA of dermatoglyphic traits in develo...

The dermatoglyphs of 50 Singapore school children with mitral valve prolapse (MVP) were studied, with special reference to the frequency of digital arches. The MVP was diagnosed clinically and substantiated by two dimensional echocardiography. In the study there were 35 Chinese and 15 Malay children, with ages ranging from 6 to 19 years. Four Chinese children had one or more arches on the digit...

The study of dermal ridges in schizophrenia has been extensive, but only recently has fluctuating asymmetry been described. This study relates dermatoglyphic patterns with the specific positive and negative symptoms of the disease in 72 DSM-III-R defined schizophrenia and 72 normal unrelated ethnically matched controls. Schizophrenic subjects had significant lower ridge counts in both hands. Fl...

The Rengma Nagas are one of the major Mongoloid tribal populations in the North-Eastern state of Nagaland in India. Population variation and sexual dimorphism in respect of finger dermatoglyphic characteristics in 207 adult individuals (104 males and 103 females) are reported in this present context. Frequency distribution of finger pattern types in different digits (both left and right sides c...

We examined dermatoglyphics of children in three Albanian and one Roma population sample (collected from 641 individuals the populations 226 both sexes). compared based on four finger (whorl, radial ulnar loop, arch) thirteen palmar traits (pattern frequencies Thenar/I interdigital area, II, III, IV Hypothenar axial »t« triradius position). The differences between were more evident for traits. ...

Abstract Background Finger dermatoglyphics has been used as a genetic marker that contributes to the detection of sports talents and establishment predisposition develop physical capacities. Additionally, it begun venture strategy in early risk factors for development chronic non-communicable diseases (CNCD), with arterial hypertension being one least studied athletes; since its prevalence is &...
