WebThe founder effect is a paucity of genetic variation attributable to small effective population size in a founding population. WebKey points: When a population is in Hardy-Weinberg equilibrium for a gene, it is not evolving, and allele frequencies will stay the same across generations. There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.
