Question

The peppered moth experiment in which black moths become predominant over white moths during industrial revolution demonstrates which of the following?

• A. Phenotypic variation and natural selection
• B. Genotypic variation and mutation
• C. Phenotypic variation and mutation
• D. Genotypic variation and natural selection

Answer 1

The correct option is A Phenotypic variation and natural selection

The peppered moth experiment showed that phenotypic variation already exists and then selection takes place due to change in the environmental conditions. Thus, black moth became predominant over white moth during industrial revolution with soot falling over the tree and white moth being predated upon more as they failed to camouflage.
