D. Both Genetics and the Environment

Explanation:

Getting a pierced ear is both a genetic and environmental trait because, in males, it is not genetically transferred, rather it is a choice to manually pierce the ear maybe at birth, or much later in life. In females, however, pierced ears is a genetic trait because it is gotten naturally when they are born

These environmental factors include where a person stays, the kind of friends they keep, and people they try to imitate. Ear piercing is something that is done manually for males for various reasons.
