What are Dimples?

6. Cleft Chin Genetics

As with cheek dimples, many geneticists suggest that chin dimples are inheritable. However, multiple claims contradict each other as to whether this is a recessive or dominant trait. The available research is fairly narrow in scope and doesn’t provide enough evidence to support chin dimples being a dominant trait. If the trait were dominant, two parents with smooth chins would not be able to have a child with a chin dimple. However, family studies show that this is possible, so chin dimples being the result of a dominant allele is likely a myth.
