1.RNA polymerase moves along the DNA unwinding the strand.

2.Hydrogen bonds between base pairs break which allows the unzipping of the double helix.

The graph below is of directional selection. Which statement can be supported by the evidence shown in the graph?
7nadin3 [17]

<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.
