Some members of a photosynthetic plant species are genetically resistant to an herbicide, while other members of the same species are not resistant to the herbicide. Which combination of events should cause the most effective replacement of the non-herbicide-resistant strain of plants by the resistant strain?

3. The maintenance of the proper conditions for one generation
4. The maintenance of the proper conditions for many generations
