Industrial melanism is an example of?
1. Neo Darwinism
2. Natural Selection
3. Mutation
4. Neo Lamarckism
In the case of peppered moth (Biston betularia), the black-coloured form became dominant over the light-coloured form in England during the industrial revolution. This is an example of:
1. | natural selection, whereby the darker forms were selected |
2. | appearance of the darker coloured individuals due to very poor sunlight |
3. | protective mimicry |
4. | inheritance of darker colour character acquired due to the darker environment |
Industrial melanism as observed in peppered moths proves that:
1. | The true black melanic forms arise from a recurring natural selection |
2. | The melanic form of the moth has no selective advantage over the lighter form in an industrial area |
3. | The lighter-form moth has no selective advantage either in polluted industrial areas or non-polluted areas |
4. | Melanism is a pollution-generated feature |
