What are Dimples?

4. Cheek Dimple Genetic Controversy

There is some controversy on the topic of inheritable dimples. Originally, genetic experts believed dimples were the result of a single gene with two alleles and that the allele for dimples was dominant. This would mean that children could easily inherit dimples from their parents. However, there is very little evidence supporting this. In reality, it is likely that dimples are the result of a gene influenced by many other genes. John McDonald, a professor of Biological Sciences at the University of Delaware, believes there is no evidence of a genetic basis for dimples.
