Abstract :Objectives: Establishing that certain traits are inherited can be assessed from the extent of morphological similarity of the offspring and their parents. This study, evaluated the pattern similarity of the fingerprint of offspring to that of their parents using a novel classification. Methods: Fifty families insert ignore into journalissuearticles values(comprising of father, mother and a child); without ethnic considerations were recruited and digital fingerprints were obtained. The fingerprints; arch insert ignore into journalissuearticles values(A);, loop insert ignore into journalissuearticles values(L);, and whorl insert ignore into journalissuearticles values(W); were identified and a novel classification insert ignore into journalissuearticles values(A, L, W, AL, AW, and LW); for heredity study as described by Aigbogun et al.insert ignore into journalissuearticles values(2018); was adopted. Chi-square analysis was used to test distribution differences, while a pedigree tree was designed for the offspring’s similarity to the parents. Results: In this study, loop insert ignore into journalissuearticles values(L); was consistently predominant both as single insert ignore into journalissuearticles values(>60%); and combined distribution insert ignore into journalissuearticles values(>75%);, followed by whorl insert ignore into journalissuearticles values(<25%); and then arch insert ignore into journalissuearticles values(<22%);; although not entirely consistent for the whorl insert ignore into journalissuearticles values(W); and arch insert ignore into journalissuearticles values(A);. The distribution except the ring finger insert ignore into journalissuearticles values(¯2=24.891; P=0.036); was not statistically significant insert ignore into journalissuearticles values(p>0.05);. From the pedigree tree, the possibility that the offspring displayed patterns similar to that of the parental combinations was 84% for the thumb, 76% for the index finger, 84% for the middle finger, 88% for the ring finger, and 92% for the little finger. Conclusion: Morphological evidence from this study suggests that fingerprints are more genetically determined than environmentally influenced; however, the pattern in which they are inherited seemed closer to co-recessivity with complex expressivity.
