Disrupting Equilibrium • 1) Mutations- a change in DNA changes allele frequencies • 2) Gene flow- genes move in and out of the population due to immigration and emigration • 3) Genetic drift is a change in allele frequencies • Genetic drift operates most strongly in small populations • 4) Non rando ...
