Dimples are usually considered a dominant genetic trait, which means that one copy of the altered gene in each cell is sufficient to cause dimples. Genetic diseases or disorders are caused due to abnormalities in the genetic makeup of an individual. There are some unexpected characteristics all right-brained people have in common, or, at least, that people tend to associate with right-brain dominance, about which you might want to know more.
