Assumptions of Hardy-Weinberg Equilibrium
What are the assumptions of Hardy-Weinberg equilibrium?
- Small population, random mating, absence of mutation, migration and selection
- Large population, non-random mating, absence of mutation, migration and selection
- Large population, random mating, presence of mutation, migration and selection
- Large population, random mating, absence of mutation, migration and selection — Correct Answer
Explanation:
Correct Answer: Large population, random mating, absence of mutation, migration and selection
H-W Law: In a large, random-mating population, in the absence of mutation, migration, and selection, the gene and genotypic frequencies remain constant from generation to generation.
H-W Equilibrium Equation
p² + 2pq + q² = 1
Where p² = freq(AA), 2pq = freq(Aa), q² = freq(aa)
Forces that Disturb H-W Equilibrium
- Mutation, Migration, Selection (Systemic — operate in large and small populations)
- Random genetic drift (Dispersive — only in small populations)
Panmixia = random mating (a condition for H-W equilibrium).
