In a Hardy-Weinberg equilibrium for two alleles A and a with frequencies p and q, which set of conditions must all be satisfied for the equilibrium to hold?
A{'text': 'No mutation, no migration, no genetic drift, random mating and no natural selection', 'label': 'A'}
B{'text': 'Only the absence of new mutations is strictly required; other forces may act freely', 'label': 'B'}
C{'text': 'Only random mating is strictly required; other forces are irrelevant to allele frequency', 'label': 'C'}
D{'text': 'Only a large effective population size is required, irrespective of selection and flow', 'label': 'D'}
Answer & Solution
Correct answer: A. {'text': 'No mutation, no migration, no genetic drift, random mating and no natural selection', 'label': 'A'}
The Hardy-Weinberg principle holds only when none of the five disturbers acts on the population: no mutation, no gene flow or migration, no genetic drift, random mating and no natural selection. Violation of any one of these shifts allele frequencies and is interpreted as evolution.
