One of the main reasons only certain people develop back dimples is genetics. These dimples are considered an inherited trait, meaning if one or both parents have them, there is a higher chance their children will, too. Scientists explain that the placement of ligaments, as well as skeletal alignment, can vary from person to person. For some, this variation naturally results in the visible indentations. For others, the ligaments are positioned differently, so no dimples appear.
