Evaluation of Palmar Crease Variant and Gender Associated Differences among Indigenes of Delta State, Nigeria

Palmar creases are lines of formation of palm. Forensic analysis of palmar crease has been linked with ancestry/ethnicity but there is dearth of literature on sex associated difference in the distribution of palmar increase. Hence, the objective of this paper was to evaluate the palmar crease variant and gender associated differences among indigenes of Delta State, Nigeria using appropriate standard procedures with Palm print of 360 subjects of 180 male and 180 female. Results obtained show that for palmar crease variant types based on the heads/pattern of origin/meeting pattern of the major creases, p-value are 0.157, 0.239 and0.239 for Types 1, 2 and 3 respectively on the right palm while on the left palm p-value are 0.157,0.240 and 0.239 for Types 1, 2 and 3respectively. For palmar crease variants based on the shape of crease, p-value are 0.239 for both Types M and V on the right palm, while on the left palm p-value are 0.239 and 0.240 for Types M and V respectively. For palmar crease variant types based on the presence of Middle longitudinal crease, p-value are 0.238 and 0.239 for Types X and Y respectively on the right palm, while on the left palm p-value for Types X and Y are 0.239 and 0.238 respectively. This study revealed that the distribution of palmar crease was independent of sex (no sexual dimorphism) and cannot be an adjunct for sex prediction.
