Dimple

Dimples are small facial kinks in between the corners of our mouths and edges of our cheeks. They aren't visible unless the mouth turns upwards (as in laughing). Some people have dimples on only one of their cheeks. Dimples are the expression of a dominant gene.

Some people have a dimple on their chins, known as cleft chin. Like cheek dimples, chin dimples are inheritable and have a varying degree of prominence. For example, while Kirk Douglas has a very conspicuous cleft chin, his son, Michael Douglas has a much less visible cleft chin. The majority of females do not have cleft chins http://www3.ncbi.nlm.nih.gov/htbin-post/Omim/dispmim?119000. The groove of the cleft chin is not just skin-deep, but also on the jawbone, as a groove in the vertical midline of symphysis menti and the soft tissue above it. It is probably the result of incomplete fusion between the left and right halves lower jaw during embryologic development http://www.madsci.org/posts/archives/sep99/938018019.An.r.html.
