Which of the following is NOT one of the factors listed in the chapter as disturbers of Hardy-Weinberg equilibrium?
A{'text': 'Gene migration between populations adding new alleles', 'label': 'A'}
B{'text': 'Genetic drift causing chance changes in allele frequency', 'label': 'B'}
C{'text': 'Random mating in a large population at allelic equilibrium', 'label': 'C'}
D{'text': 'Natural selection acting on heritable phenotypic variation', 'label': 'D'}
Answer & Solution
Correct answer: C. {'text': 'Random mating in a large population at allelic equilibrium', 'label': 'C'}
The chapter lists gene migration or gene flow, genetic drift, mutation, genetic recombination and natural selection as the five factors that disturb Hardy-Weinberg equilibrium. A large randomly mating population with no other forces in operation is precisely the condition under which the equilibrium holds.
