A Genetic Trait: Dimples In many eyes, dimples are considered a mark of beauty and loveliness. In an article by Manali Oak she describes "Dimples" almost perfectly. According to Oak, "Technically speaking, dimples are observable cavity created as a result of the underlying flesh of the cheeks. It is very difficult to understand that dimples are the outcome of a birth defect resulting from a diminished facial muscle. A dimple is the result of a defect in the subcutaneous connective tissue that unfolds during embryonic development. Also, a variation in the structure of the facial muscle zygomaticus major is known to cause dimples. When a person smiles, the smaller muscles on his/her face cause the facial skin to get extracted, thus resulting in a slight indention in the skin, a dimple. A tug in the skin of a human's chin caused by a condensed chin muscle, results in a dimpled chin.How is dimple formation related to genetics? Dimples are a dominant genetic trait and are inherited from one generation to another. Dimples on both cheeks are a normal matter, while a single dimple that takes place on one side of the face occurs every blue moon. As dimples are a dominant trait, only one gene is allowed to receive dimples.The gamete cells created through meiosis previous to the process of reproduction can accommodate genes that create dimples, or genes that produce the muscles manage dimples. During reproduction, each parent supplies one of these genes to the child. Since the dimple gene is dominant, a child has dimples if the gene is received. It means that if both your parents have dimples, you have 50-100% chances of inheriting dimple genes. If one of the parents possesses dimples, there are 50% chances that their children will acquire dimples. If both the parents do not have dimples, there are zero chances that their children will receive dimples. Nonetheless, their children can give recessive dimple
