[Campbell Biology P.553] Which of the following is NOT a condition required for a population... | Practice Question

Which of the following is NOT a condition required for a population to be in Hardy-Weinberg equilibrium?

  • A: Large population size
  • B: Random mating
  • C: Presence of natural selection
  • D: No gene flow
  • E: No mutation

Explanation

For a population to be in Hardy-Weinberg equilibrium, there must be NO natural selection, as natural selection causes allele frequencies to change by favoring certain traits. The other options listed large population size, random mating, no gene flow, and no mutation are all conditions necessary for equilibrium.
