Which is not a requirement for natural selection to occur?
Lisa [10]

Three, if the population is infinitely large. Four, if all the members of the population produce offspring.  Five, sexual intercourse is random. Six, the population will produce the same number of offspring. And lastly, the population does not migrate from one place into the other. The thing that would disrupt the genetic equilibrium is the mutation.
