Which of the following is an example of environmental variation? A. Ayo is a tongue roller B. Margaret dies her hair blue C. John inherited baldness D. Paul and Peter have hanging ear lobes
Correct Answer
Option B is the correct answer.
Detailed Explanation
Environmental variation refers to differences caused by external factors, not genes. Dyeing hair blue is a choice, an environmental factor. Tongue rolling, inherited baldness, and ear lobe type are genetic traits.
Hint
It's something done to the body, not inherited.
