Do your ears hang low?

Earlobe Type & Genetics

Many people only think about earlobes when they're deciding which earrings to wear, or when buying earrings as a gift. Generally, earlobes are either attached to the side of the head, or detached and only connected to the ear itself. You might be surprised to learn that earlobe shape is influenced by dozens of genetic factors.

How it works

Scientists don't know why people have earlobes, but that hasn't stopped them from trying to understand which factors impact earlobe shape.

The genetic link

Hopefully everything you learned in science class didn't go in one ear and out the other. But when it comes to earlobe type, it might be okay if you've forgotten what you learned in school. That's because it was once commonly believed that a single gene influenced earlobe shape. 23andMe researchers have looked at 34 genetic markers that influence earlobe type.

Did you know?

The fact that this seemingly simple trait is much more complex than once thought could yield insights into serious genetic conditions that affect the face. That's why genetic researchers are crying "lend us your ears" over new findings on earlobe shape.
