STUDY TITLE: Genome-wide association study reveals sex-specific genetic architecture of facial attractiveness
SUMMARY: Identification of 2 novel genetic variants that are associated with facial attractiveness.
OVERVIEW: Facial attractiveness is a complex human trait. Though commonly attributed to sociological factors, there are different genetic factors that influence facial beauty in males and females. This genome-wide association study identified 2 sex-specific genetic variants associated with facial attractiveness by examining over 4,000 individuals of European ancestry. Additionally, the study uncovered associations between the identified variants and tissues involved in reproduction and hormone production. Furthermore, the study found that for females, a high body mass index (BMI) was correlated with lower facial attractiveness, while for males, facial attractiveness was correlated with blood cholesterol levels which are known to be involved in the synthesis of testosterone.
DID YOU KNOW? Facial beauty tends to be positively associated with symmetry. People also tend to find familiar faces attractive. [SOURCE]
