"Directional selection" will most likely occur.
<u>Answer:</u> Option B
<u>Explanation:</u>
Directional selection or positive selection is an organic selection mechanism in population genetics, this scrutiny is an intense phenotype is preferred over certain phenotypes, allowing the intensity of the allele to migrate over moment towards that phenotype.
For an instance directional selection are fossil statistics showing that the scale of black bears in Europe diminished throughout ice ages interglacial phases however grew at each glacial period. A further example is the scale of the beak in a finch group.
