Antihelical Ossified Granule: A Recently Identified Potentially Inherited Human Trait in the Auricular Concha – A Case Study

Abstract

In the early stages of research on the genetics of human morphological traits, particular attention was given to the details of the physical complexities of the face. In this field, prominent focus was placed on the characteristics of the auricle, especially the types of the earlobe (lobulus auriculae). This paper presents the first data on the previously undescribed possibility of inheriting the ossified granules of the antihelix. Based on genealogical analysis of the presence/absence of the granule across five successive generations of a Bosnian family, evidence is provided for the autosomal recessive inheritance of this dimorphism.
