Digital and palmar dermatoglyphics in Greeks

Area of Science:

• Anthropology
• Human Genetics
• Forensic Science

Background:

• Dermatoglyphics, the study of skin patterns, offers insights into human population genetics.
• Previous dermatoglyphic studies have established baseline frequencies for various ethnic groups.

Purpose of the Study:

• To determine the dermatoglyphic frequencies of two distinct Greek populations.
• To compare these frequencies between sexes and geographical origins within Greece.
• To assess the overall dermatoglyphic profile of the Greek population in relation to other Caucasian groups.

Main Methods:

• Collection of dermatoglyphic data (fingerprints and palm prints) from two Greek samples: adult island inhabitants and school children.
• Statistical analysis of digital pattern frequencies, D line modal types, Sydney creases, and accessory axial triradii.
• Comparative analysis between sexes and pooled samples, and with existing Caucasian population data.

Main Results:

• No significant dermatoglyphic differences were found between males of the two Greek samples.
• Significant differences in digital pattern frequencies, D line modal types, and Sydney creases were observed exclusively in females.
• Despite female variations, the combined Greek sample's dermatoglyphic frequencies generally matched Caucasian population means.
• Greeks exhibited higher frequencies of accessory axial triradii and complete Sydney creases compared to other Caucasian populations.

Conclusions:

• The dermatoglyphic variations in Greek females were insufficient for sample discrimination.
• The pooled Greek sample represents a cohesive dermatoglyphic profile within the broader Caucasian range.
• Elevated frequencies of accessory axial triradii and complete Sydney creases are characteristic of the Greek population studied.
