Are dimples genetic?

Yes, dimples are largely genetic, often considered a dominant trait, but the inheritance is complex, involving multiple genes and sometimes appearing unexpectedly, as they stem from variations in facial muscles, like the zygomaticus major, causing skin to pull inward during smiles. While they run in families, the exact genetic mechanisms are still being studied, and sometimes they appear even if parents don't have them, possibly due to fat in the cheeks or new mutations.

What causes a person to have dimples?

Dimples are usually caused by a variation in the facial muscle called the zygomaticus major, which splits into two bundles instead of one, pulling the skin inward to create an indentation when smiling. These are considered a genetic trait, often inherited, and can appear on cheeks, chin, or lower back, though chin dimples form differently (from jawbone fusion). Some dimples, especially in babies, are due to fat and may disappear as the face matures.
