Summary
This study reveals a significant correlation between fingerprint ridge density and hand dimensions in North Indian adults. These findings can help predict hand size from fingerprints and vice-versa.
Area of Science:
- Forensic Science
- Anthropometry
- Dermatoglyphics
Background:
- Previous research extensively explored various aspects of fingerprint analysis.
- The specific correlation between fingerprint ridge density and hand dimensions remained undocumented.
Purpose of the Study:
- To investigate the relationship between fingerprint ridge density and hand dimensions.
- To establish conclusions regarding this association for potential applications.
Main Methods:
- Study involved 500 adults (250 males, 250 females) aged 18-25 from North India.
- Sexual dimorphism in ridge count was analyzed using Student's t-test.
- Pearson's correlation coefficient assessed the relationship between ridge density and hand dimensions.
Main Results:
- Statistically significant sex differences were observed across all fingers.
- Weak to strong correlations were found between specific digits and hand length/breadth.
- Pooled data demonstrated highly significant correlations between all digits and hand breadth.
Conclusions:
- Fingerprint ridge density correlates with hand dimensions in the studied population.
- Prediction equations can be developed to estimate hand dimensions from ridge density, or vice-versa.
- These equations offer a method for estimating anthropometric measurements based on fingerprint characteristics.

1.0K
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the...

01:18Polygenic Traits
66.2K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...
