Anatomical Survey of Dermatoglyphic Patterns in Identical and Fraternal Twins at the University of Lagos

Dermatoglyphics is the scientific study of epidermal ridge patterns on the fingertips, palms, and soles. These patterns are genetically determined, formed during the third to fifth month of foetal development, and remain unchanged throughout life. Comparing dermatoglyphic patterns in monozygotic (identical) and dizygotic (fraternal) twins provides valuable data on the heritability of these patterns and their relevance in forensic identification, clinical genetics, and anthropology. This study aims to document and compare fingerprint patterns, palmar ridge counts, and atd angles in monozygotic and dizygotic twins attending the University of Lagos Medical Centre, South West Nigeria. Ink impression methods will be used to collect fingerprint and palm prints from consenting twin pairs. Pattern types, including loops, whorls, and arches, will be classified using standard protocols, and comparisons made between the two twin types. The study anticipates elucidating the extent of genetic influence on dermatoglyphic features within the Lagos population and producing a data set useful for forensic casework and genetics education in South West Nigeria.
