Question

Change in frequency of alleles in a population results in evolution as proposed by :

• A. De Vries theory
• B. Hardy-Weinberg principle
• C. Darwin's theory
• D. Lamarck's theory

Answer 1

Answer: (B)

Hardy-Weinberg principle

• According to Hardy-Weinberg principle, disturbance in genetic equilibrium or change of frequency of alleles in a population can be interpreted as accumulation or change in variations that results in evolution.
  
• Five factors are known to affect Hardy-Weinberg equilibrium,

1. Gene migration or gene flow

2. Genetic drift.

3. Mutation.

4. Genetic recombination.

5. Natural selection.

So, the correct answer is 'Hardy-Weinberg principle'
