Answer:
e) directional selection
Explanation:
Directional Selection:
- The type of natural selection that favors one of the extremes of the phenotype spectrum, shifting the allele frequency to one direction
- This type of selection selects against intermediate and one of the extreme phenotypes.
- In this particular case, the increasing pollution has pushed the plants to evolve better acid tolerance.
- This indicates that if the environmental conditions worsen, only the acid tolerant plants will be able to survive.
* Another example is illustrated in the image. The graph shows the shifts in allele frequency.
When two experiments are identical except for one variable, the experiment is called a controlled experiment
