Question

Industrial melanism as observed in peppered moth proves that

• A. The dark melanic form of the moth has no selective advantage over lighter form in industrial area
• B. The ligher-form moth has no selective advantage either in polluted industrial area or non-polluted area
• C. Melanism is a pollution-generated feature
• D. The lighter form moth has an advantage in the non-polluted area but the dark moth has the advantage in the polluted area

Answer 1

The correct option is D The lighter form moth has an advantage in the non-polluted area but the dark moth has the advantage in the polluted area

After industrialisation, white peppered moths used to sit in the lichen-less (as lichen are present in non-polluted areas) tree bark where it could be easily identified by predators. But the black peppered moths can easily hide. So, the lighter form moth has an advantage in the non-polluted area but the dark moth has the advantage in the polluted area.

Thus, the correct option is D.
