Inherited facial traits

About video
Some genetic disorders are more likely to occur among people who trace their ancestry to a particular geographic area. People in an ethnic group often share certain versions of their genes, which have been passed down from common ancestors. If one of these shared genes contains a disease-causing mutation, a particular genetic disorder may be more frequently seen in the group. Examples of genetic conditions that are more common in particular ethnic groups are sickle cell disease , which is more common in people of African, African American, or Mediterranean heritage; and Tay-Sachs disease , which is more likely to occur among people of Ashkenazi eastern and central European Jewish or French Canadian ancestry. It is important to note, however, that these disorders can occur in any ethnic group.

Hereditary facial features could be strongly influenced by a single gene variant -- ScienceDaily

Last Updated on September 9, Traits are inherited and passed from parent to child through their genes. Some are passed from the mother and some from the father. Others depend on what traits are most prominent in both the parents, if they are dominant traits and if they run in the family. In a baby, there are certain traits belonging to both the parents that he will adopt.

The Most Attractive Facial Traits According To Science

Researchers have identified five of the genes that shape a person's face, work that could help scientists better understand facial abnormalities like cleft palate and someday might even help forensic investigators determine what a criminal suspect looks like from crime-scene DNA. Researchers previously knew that genetics played a large role in determining face shape, since identical twins share DNA. However, little was known about exactly which genes are involved. Three genes were thought to have roles in the arrangement of facial features, and the new research confirmed their involvement.

Face to face is how we mostly recognise and communicate with each other. The recognition of individual faces is only possible because the human face is so hugely variable. The extreme facial likeness of identical twins, who inherit the same versions of each gene from each of their parents, and so have identical genotypes, shows that the various facial features by which we recognise people are inherited. This means that they are mostly determined by the particular combinations of genetic variants inherited from their parents. By genetic variant we mean a version of a particular gene that differs from other versions of the same gene at a given position in the DNA.
