WebSep 12, 2024 · September 12, 2024 by Alexander Johnson. Positive selection is the process by which new advantageous genetic variants sweep a population. Though positive selection, also known as Darwinian selection, is the main mechanism that Darwin envisioned as giving rise to evolution, specific molecular genetic examples are very difficult to detect.

Introduction. Artificial selection is the process by which humans choose individual organisms with certain phenotypic trait values for breeding. If there is additive genetic variance for the selected trait, it will respond to the selection, that is, the trait will evolve.
