bilateral finger and palm prints of 500 males and 500 females of the caucasian origin in south iran have been collected and analyzed for both qualitative and quantitative dermatoglyhic features. results show that most of the qualitative features on bilateral and bisexual differences are not significant. however, quantitative features frequently showed significant differences both bilaterally an...

various dermatoglyphic parameters like finger print pattern, atd angle, absolute ridge count & ab, bc ,cd, and ad ridge counts were observed in 150 cases of congenital cardiac disease, comprising of 72 cases of ventricular septal defects (vsd), 60 cases of atrial septal defects (asd), 9 cases of coarctation of aorta (coa) & 9 cases of tetralogy of fallot’s (tof). same dermatoglyphic parameters ...

Three dermatoglyphic traits, viz; finger patterns, finger ridge counts, and palmer a-b ridge counts of 57 (M-29; F-28) and 64 (M-29; F-35). Schizophrenics with and without positive family history respectively, and 65 controls (M-30, F-35), were analysed to determine their level of fluctuating asymmetry.Uniformly higher fluctuating asymmetry was observed in the loop ridge counts of second digits...

The purpose of this study was to follow Acree’s 1999 theory and demonstrate that there are significant differences in the loop ridge count of male subjects compared to that of female subjects. This was based on the belief that women tend to have finer ridge detail, therefore more ridges, while men have coarse ridge detail, thereby fewer ridges [1]. This study, in contrast to Acree’s methodology...

Su~mary. A genetical analysis of variation in finger ridge counts of221 pairs of twins and 80 pairs of opposite sex siblings has been carried out. Negative regression ofDZ and sibling pair variances on pair means suggests the action of non-additive genes or unequal gene frequencies tending to increase finger ridge counts. Negative skewness of the distributions supports this view. While models i...

finger patterns and ridge-counts in a random sample of iranian muslims consisting of 100 males and 100 females are described. the most common finger patterns found were loops, having a frequency of 54.4% u.l., 3.4% r.l. in males and 51.2% u.l. and 4.8% r.l in females. the frequencies of arches and whorls in both sexes were 4% and 38.5% respectively. bimanual and sex differences were indistinct....

Finger ridge count is a valuable quantitative phenotype used in a wide range of biological and anthropological research. However, the scoring of the phenotype is both labour intensive and error prone. This paper describe a freely available software program, RIDGECOUNTER, that can be used to obtain ridge counts from digitized prints (either collected using a digital fingerprint scanner or scanne...

The finger ridge count (a measure of pattern size) is one of the most heritable complex traits studied in humans and has been considered a model human polygenic trait in quantitative genetic analysis. Here, we report the results of the first genome-wide linkage scan for finger ridge count in a sample of 2,114 offspring from 922 nuclear families. Both univariate linkage to the absolute ridge cou...

Several years ago the distributions of the ridge-counts on all ten fingers were given for a small sample of unrelated persons (Holt, 1949). A more detailed analysis has recently been made of the digital counts of a population sample of 1650 persons, 825 males and 825 females, and the results are given here. Included in the sample are the 100 males and 100 females whose counts were used previous...
