Heritability of the Carabelli Cusp in Twins

The study of the Carabelli trait among 199 monozygotic and dizygotic twin pairs failed to demonstrate a high degree of heritability. Analyses of antimere differences in individuals indicated a lack of mirroring and no sexual dimorphism. Monozygotic twin pairs exhibited a higher concordance rate for corresponding tooth comparisons than dizygotic twin pairs.
