Can the thickness of eyebrows be inherited?

Yes, the thickness of eyebrows can be inherited. Eyebrow thickness is a polygenic trait, meaning that it is influenced by multiple genes. Studies have shown that there is a genetic component to eyebrow thickness, and that certain genes are associated with thicker or thinner eyebrows. For example, one study found that a variant of the EDAR gene was associated with thicker eyebrows. Additionally, eyebrow thickness has been linked to other genetic traits, such as hair color and skin tone.
