Background:
Forensic sciences deal with key areas to be included in judicial makeup that has been approved by both the court and the scientific community, which distinguishes truth from counterfeit. Lip and palmprints are one of a kind and do not change during the lifetime of a person unless any pathologies.
Objectives:
To evaluate the heritability, and gender dimorphism of lip and palm prints among parents and their offspring.
Methods:
A total of 280 participants were included in the study. Lip and palm prints were collected from participants using a digital camera. The photographic data obtained is subjected to Adobe Photoshop and analysed for inheritance. Gender dimorphism is evaluated by the predominant lip pattern and palm ridge count in four designated areas.
Results:
A positive resemblance of 28.4% was found between parents and offspring in lips, and for the right palm, it was 60.2% and 55.12% for the left palm (principal lines) which are statistically insignificant. In all six quadrants, the most predominant lip pattern found in males is type 5, and in females, type 11. The mean palm ridge density was significantly higher among females than males in all designated areas.
Conclusion:
The digital method of analysing lip and palm print images with Adobe Photoshop 7 software is a convenient method that allows for better visualisation and easier lip and palm print recording and identification. Considerable inheritance patterns and gender dimorphism were observed that aid in personal identification.

Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used;...
