Infinite sites model

The Infinite Sites Model is a concept used in population genetics, particularly in the context of genetic mutation and variation. In this model, it is assumed that there are an infinite number of possible genetic loci (sites) that can mutate. Each locus can mutate independently, and each mutation is considered to create a new, unique genetic variant. This means that over time, as mutations accumulate, the genetic diversity in a population can increase without limit, due to the assumption of infinite sites.
