cleft chin..........
Cleft chin is a facial characteristic that looks like a dimple or an indentation to a person’s chin. It is caused by the failure of the lower half of the jaw to fuse together during fetal development. It is an inherited physical trait which is observed more prominently in men than in women. In the general population, the number of people with cleft chins is lower than those with the normal chin (it doesn’t mean that people with cleft chins are “abnormal”, they are in fact attractive). Like any of our facial characteristics (dimples, broad forehead, hook nose, etc.), genetics is what causes cleft chin.
In theory, parents with cleft chins would have children with cleft chins since the trait is dominant. On the other hand, parents that do not have the cleft chins could not have children with the trait since they do not carry the genes for cleft chin. However, these instances are not always observed. It can happen that parents with cleft chins couldn’t produce children with the trait and parents with no cleft chins could produce children with the trait. These phenomena are due to variable penetrance or the presence of modifier genes.
