It is a result of asexual reproduction. It is a result of childhood nutrition. It is an inherited characteristic. It is a personal choice.
I gave my students this multiple choice question: A 13-year-old boy has blue eyes. Which statement concerning his eye color is correct?

Only one answer is correct among these 4 choices:
- It is a result of asexual reproduction.
- It is a result of childhood nutrition.
- It is an inherited characteristic.
- It is a personal choice.

Could you tell me which one is correct?

It is an inherited characteristic.
