They all have dimples or, as they were originally called, gelasin—a visible indentation anywhere on the skin. They have dimples on their chin. And whether you are a fan of dimples or not, you do have to admit to having thought about what causes dimples and why some individuals have them and others do not. Some cultures believe that it is a sign of good fortune and prosperity. But it is also interesting that a small indentation on each side of the face that appears as soon as a person smiles is reason to find that as well as the individual endearing.

Dimples—indentations on the cheeks—tend to occur in families, and this trait is assumed to be inherited. Dimples are usually considered a dominant genetic trait, which means that one copy of the altered gene in each cell is sufficient to cause dimples. However, some researchers say that there is no proof that dimples are inherited. Little research has been done to explore the genetics of dimples and it is not known which gene or genes may be involved. A dimple is an anomaly of the muscle that causes a dent in the cheek, especially when the individual smiles.

Does the dominant allele for a given trait show up as the prevalent phenotype in the population at large? For example, the presence of dimples is controlled by a dominant allele, but the majority of people do not have dimples. Why is this? As you've noticed, dominant does not mean common. Dominant just means that it'll win out over recessive. How common a trait is has nothing to do with this.

Introduction: If both of your parents have dimples small dents in the cheek, which become prominent when you smile , do you think you ll have dimples or not? In general, you are likely, but not guaranteed, to have dimples. This is because having dimples is a dominant trait. Genetics is the study of how certain features are transferred from generation to generation. Not all characteristics are passed through inheritance. For example, if you have black hair but dye your hair green, that doesn t mean your children will have green hair.

Observable Human Characteristics

Dimples are small indentations that can be found on your skin. They can occur on different places of the body, including the cheeks, chin , and lower back. Cheek dimples can be found on the sides of the mouth.

  1. Hello, I am trying to understand more about the gene that is responsible for cheek dimples and chin dimples.
