I looked through a gallery of United States Senators (because they have large official portraits online) and picked out the ones that had some hint of a cleft chin, along with a few smooth-chinned senators for comparison. Some evidence indicates that cleft chins are partially influenced by environmental factors. Inheritance of human facial features: a pedigree study involving length of face, prominent ears and chin cleft. Why modern humans have this particular feature and why it is not present in any fossil or living primate remain tantalizing questions.
Many people have chins that are intermediate between clearly cleft and clearly smooth, and the family studies do not fit the myth that cleft chin is caused by a dominant allele. In the general population, the number of people with cleft chins is lower than those with the normal chin (it doesnt mean that people with cleft chins are abnorm… Some say freckles come from the kiss of an angel.

Hereditas 46: 543-569.Bhanu, V., and K.C. Sam Elliott Married To Whoopi Goldberg, They said there was no difference in frequency of cleft chin among age groups, using a Lebow and Sawin (1941) first suggested that cleft chin was a genetic character, based on data from a single family. It is caused by the failure of the lower half of the jaw to fuse together during fetal development. Robert Franciscus takes a more anthropological viewpoint: he believes that the chin was formed as a consequence of the change in lifestyle humans underwent approximately 80,000 years ago. Did you know humans are the only animals to have chins?
A further challenge to predicting cleft chins is that scientists have yet to study the genetics of chin shape extensively.
