In any case, there is an interesting reason how some people develop the dimple and some don't.

The dimple happens to be a result of asymmetry in the jaw line.

For those born with it, the jaw develops as two separate halves on a foetus and when there is slight deviation in alignment during the fusing of the two halves it results in cleft chin. While, those who develop it usually have it because one half of the jaw grows larger or longer than the other, causing the dimple at the chin where the two halves fuse.
