What are the assumptions of Hardy-Weinberg equilibrium?
Options
Small population, random mating, absence of mutation, migration and selection
Large population, random mating, presence of mutation, migration and selection
Large size population, random mating, absence of mutation, migration and selection ✓
Small population, non-random mating, absence of mutation only
Correct Answer: C
Explanation in English
Correct Answer: Large population, random mating, absence of mutation, migration and selection
From the notes: Hardy-Weinberg Law: In a large, random-mating population, in the absence of mutation, migration and selection, gene and genotypic frequencies remain constant from generation to generation.
All Five Assumptions
Large population size — eliminates random genetic drift
Random mating (Panmixia) — no assortative mating or inbreeding
No mutation — no new alleles being created
No migration — no gene flow into or out of the population
No selection — all genotypes have equal fitness
Forces that Disturb H-W Equilibrium
Systematic forces: Mutation, Migration, Selection (act in large and small populations)
Dispersive force: Random genetic drift — acts only in small populations
