Genetics of dermal ridges; the relation between total ridge-count and the variability of counts from finger to finger.
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...
متن کاملA genetical analysis of covariation between finger ridge counts.
1. The genetical and environmental structure of covariation between finger ridge counts in twin and sibling data has been analysed using the method of Martin and Eaves (1977) adapted from Jöreskog. 2. The model for environmental covariance contains a single factor loading on all ten digits but most environmental variance is specific to each finger. 3. For additive genetic variance there is one ...
متن کاملRidgecounter: a program for obtaining semi-automated finger ridge counts.
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...
متن کامل"a dermatoglyphic study of iranaian muslims part i: finger patterns and ridge-counts "
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....
