Biology

When artificial selection is used to select for specific traits (such as larger fruit, better yield, or disease resistance), it often results in a population with less genetic diversity. With less diversity, the population has fewer options to adapt to environmental changes, such as new pests or climate shifts.

For A: Artificial selection typically **reduces** genetic variation because it involves selecting specific traits to breed for, often narrowing the gene pool to a small number of desirable traits.
