A facial deformity known as “Habsburg jaw,” famously noted in the Habsburg dynasty of Spanish and Austrian royals, can be attributed to inbreeding.

According to a new study published in the Annals of Human Biology that looked at facial deformities and investigated the possibility of a genetic basis for them, the unique chin is a result of generations of intermarriage.

“The Habsburg dynasty was one of the most influential in Europe, but became renowned for inbreeding, which was its eventual downfall. We show for the first time that there is a clear positive relationship between inbreeding and appearance of the Habsburg jaw,” said lead researcher Professor Roman Vilas from the University of Santiago de Compostela in a statement.

Researchers recruited 10 maxillofacial surgeons to diagnose facial deformity in 66 portraits of 15 members of the Habsburg dynasty. The surgeons were able to diagnose 11 features of mandibular prognathism, also known as “Habsburg jaw,” as well as seven of maxillary deficiency, most recognized by a prominent lower lip and overhanging nasal tip.

Remember John Boy’s surgery? Before and after…I jest of course!
