The term selective sweep encapsulates a powerful idea in population genetics: when a new, advantageous genetic variant arises, natural selection can drive it to high frequency in a population. As it increases, the neighbouring DNA segments “hitchhike” along, reducing genetic diversity in that region and leaving a distinctive mark across the genome. This signature, a…
