<u>Answer</u>: C) Directional selection occurs when one of two extreme phenotypes is selected for.
The type of natural selection known as directional selection is defined in population genetics in the case in which an extreme phenotype is favored over other phenotype. Thus, the population and its allele frequency will evolve towards this end of the trait spectrum (extreme phenotype). This is also the case illustrated in the graph where the right side represents the extreme phenotype.
Answer: The given statement is False.
The range of motion can be defined as the angular or linear distance that an object in motion may normally travel while attached to another object.
In the given question, the two objects are separated from each other. Therefore, the condition of the range of motion is not satisfied. Hence, it is a false statement.
