Are Dimples attractive to you or not?? I happen to only have one dimple so I am defective I guess.lol
The genetics of dimples is actually rather interesting. They are a dominant trait, which means that it only takes one gene to inherit this defect. If neither parent has dimples, their children shouldn't have them either, unless they experience a spontaneous mutation. If one parent has them, the child has a 25-50% chance of inheriting the gene, since it means that parent inherited the gene from one or both parents. If both parents have dimples, the child has a 50-100% chance of inheriting the gene, depending on how the parents inherited theirs.
In most cases, facial dimples appear on the cheeks, although they can also pop up on the chin, and they are typically not visible until someone smiles because of how the muscles are used. Some people only have a dimple on one side, however, and some people find this physical trait to be rather endearing. The look of dimples can also vary; as an inherited trait, unusual ones can be passed on through multiple generations of a family.
Because dimples can fade with time as someone's facial muscles stretch out, many people associate them with youth. Children are referred to as having dimpled cheeks, for example, and someone who has them may be thought of as youthful or baby faced.
