Multiple Choice

Why did the melanic form (black phenotype) of peppered moth decrease in frequency after the industrial revolution?

• A mutation occurred that turned them white reducing the melanic form (black moth) population.

• Less soot and smog on trees which meant they could be seen easily by the predator.

• There was more soot and smog which meant they could more easily camouflage hence reducing the numbers of individuals that were counted.

• Both the melanic form and white form of peppered moth remained the same in frequency over time.
