Question

Quizplus · Accepted Answer

Directional selection is a form of natural selection in which an extreme phenotype is favored over other phenotypes, causing the allele frequency to shift over time in the direction of that phenotype. In the case of breeding dachshunds, breeders selectively bred individuals that exhibited the desired trait of a long body and short legs more intensely over generations, which is a classic example of directional selection applied in artificial selection.
