Solve & explain briefly

Solve & explain briefly The change of the lighter-coloured variety peppered moth (Biston betularia) to its darker variety (Biston carbonaria) is due to (1) Mutation (3) Genetic isolation (2) Regeneration Temporal isolation

Dear student,

Light-coloured variety of peppered moth (Biston betularia) changes to darker variety (Biston carbonaria) by the process of industrial melanism which allows them to hide from predators. This change from lighter colour to darker colour takes place due to mutation of the single Mendelian gene.

Therefore, the correct option is 1.

Regards,

Dear student,

Pls find the answer below for the asked query:

The change in the colour of peppered moth is due to the mutation of single mendelian gene for the survival in the smoke-laden industrial environment. It is called Industrial melanism.

So, the correct option is (1) Mutation.
