प्रश्न
According to the Hardy-Weinberg principle, the allele frequency of a population remains constant. How do you interpret the change of frequency of alleles in a population?

उत्तर
If the Hardy-Weinberg equilibrium/genetic equilibrium is disturbed it would result in evolution. In other words, change in frequency of alleles can be interpreted by evolution. Gene flow, genetic drift, mutation, etc. are some of the disturbances which may lead to change in allele frequency.
