Determine what kind of variation is related to the following trait: Pierced Ears. A. Only Environmental variation
B. Neither
C. Only Genetics
D. Both Genetics and the Environment

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.
