Cheek Dimples in Babies: A Temporary Adornment
When it comes to adorable features, cheek dimples in infants often steal the show. These charming little indentations are commonly seen in babies due to their plump cheeks, which are rich in baby fat. However, as a baby grows and develops, the presence of dimples may start to fade away. While some children manage to preserve their dimples well into their teenage years, others may witness their disappearance as they reach adulthood. This phenomenon can be attributed to the ever-changing dynamics of facial muscles and fat throughout an individual’s growth and maturation.
The Controversy Surrounding Cheek Dimple Inheritance
When it comes to the heritability of cheek dimples, there is a significant amount of controversy. Initially, genetic experts proposed that dimples were controlled by a single gene with two different versions, or alleles, and that the allele responsible for dimples was dominant. This theory implied that individuals could easily inherit dimples from their parents. However, the supporting evidence for this idea is scarce. In reality, it is more likely that dimples are influenced by a combination of multiple genes. John McDonald, a respected professor of Biological Sciences at the University of Delaware, is of the opinion that there is no substantial evidence to suggest a genetic basis for the presence of dimples.
