Abstract | The shape of the earlobes has a variety of genetic significance. This study analyzed the frequencies of the earlobe shapes in the Korean population. Data were collected on randomly selected 500 males and 500 females in Daegu Metropolitan City, with all participant ages being in their twenties. Obtuse angled earlobes accounted for 41.2% of the earlobes observed, while acute angled earlobes prevalence was calculated at 38.8% and right angled earlobe was 20.0% of the total (sexes combined). In men, the acute angled earlobe was the most frequent type (43.0%), while the obtuse angled earlobe was the most frequent type in females (45.2%). These differences were statistically significant (p = 0.015). Overall, attached type earlobe (61.2%) was more frequent than free type earlobe. The attached type earlobe was more common in both sex groups (57.0% in male and 65.4% in female), and the proportion was significantly higher for females (p = 0.006). In conclusion, the findings in this study suggest that the attached earlobe type is the most common among Koreans, and the proportion of earlobe types among males and females is significantly different. Further studies are needed to understand the genetic background of earlobe types among Koreans. |
