Question

Industrial melanism as observed in peppered moth proves that ______.

पर्याय

• the melanic form of the moth had selective advantage over lighter form in industrial area

• the lighter moth has no selective advantage either in polluted industrial area or non-polluted area

• melanism is a pollution-generated feature

• the true black melanic forms arise by a recurring random mutation

Answer 1

Industrial melanism as observed in peppered moth proves that the melanic form of the moth had selective advantage over lighter form in industrial area.

Explanation:

Soot-darkened trees camouflaged the dark moths, reducing predation. The black form arose by mutation; pollution changed which form had the advantage.
