Abstract

Introduction: The earlobe is formed by tough areola and adipose tissue, lacking the firmness and elasticity of the rest of the ear auricle. The study of earlobe attachment, as a morphogenetic trait can be used to investigate the diversity that arises within and among different populations due to genetic variations

Materials and Methods: The present longitudinal randomized study was carried on randomly selected 100 families, residing in Sriganganagar Rajasthan. Digital camera, USB Cable and laptop were used for the study.

Results: Out of total 158 offspring 86.08% are free and 13.92% are attached. Males and females displayed the highest frequency of free earlobes. There is no significant gender difference in the pattern of earlobe attachment.

Conclusion: The free earlobe is more predominant than attached earlobe and this study investigated an inheritance pattern of simple dominance recessive pattern where free earlobes are dominant over attached earlobes.
