A chin dimple, or cleft chin, can be hereditary, and passed down in what is known as a dominant trait. Our parents each give us one version of the gene involved in this trait. The two versions are not equal: ‘dominant’ means that the inheritance of just one copy of the cleft version will give you a chin cleft of some description.
A cleft in chin, also know as a dimple chin, superhero chin or butt chin is an inherited trait. It is a Y-shaped fissure that looks like a dimple or an indentation on the individual’s chin. And in an individual with a cleft chin, the underlying jaw bone has a similar structure.
The genetics behind cleft chins used to be thought of as simple. Cleft chins were believed to be a dominant trait: if two parents had cleft chins, their kids could have a cleft or might not. And if two parents had smooth chins, their kids would always have smooth chins.
16 cze 2024 · Understanding how genetics works helps in predicting the likelihood of having a cleft chin and in appreciating the diversity of chin shapes. Notable research by Bhanu and Malhotra highlights significant variation in cleft chin prevalence across populations and ages.
20 gru 2023 · A cleft chin, also known as a dimple chin, is a facial trait that is determined by genetics. It is characterized by a visible indentation or groove in the center of the chin. This trait is caused by a dominant gene, meaning that it only takes one copy of the gene for a person to have a cleft chin.
30 paź 2016 · The truth is that dimples are actually genetic defects that are caused by shortened facial muscles. Dimples are caused by a fault in the subcutaneous connective tissue that develops in course of the embryonic development.
Orofacial clefts (OFCs) are the most common congenital craniofacial anomaly seen in humans. Most OFCs are sporadic and isolated - these are thought to be multifactorial in origin. Chromosomal and monogenic variants account for the syndromic forms and for some of the non-syndromic inherited forms.
