Artificial selection refers to what process?

Artificial selection refers to the process where humans intentionally breed certain individuals of a species to enhance desirable traits in future generations. This selective breeding can apply to a variety of organisms, including plants and animals, with the aim of producing offspring that exhibit specific characteristics, such as increased yield in crops or particular physical traits in domesticated animals.

This process is distinct from natural selection, where environmental pressures and survival challenges dictate which individuals reproduce. Instead, in artificial selection, humans make choices about which organisms to mate based on observable traits deemed beneficial or desirable. This leads to a targeted enhancement of specific traits within a population much faster than would occur through natural evolutionary processes alone.

Other options presented do not accurately describe artificial selection. Random genetic mutations refer to natural changes in the genetic material that occur without any deliberate human intervention. Natural selection over time describes the mechanism by which species evolve due to environmental pressures without human influence. Genetic drift pertains to random changes in allele frequencies within small populations, which also does not involve human selection of traits.
