If we consider Hardy-Weinberg law, then following is incorrect in its sense?
Correct answer: D. Non-random mating will reduce chances of evolution.
- A. Mutations cause changes in genetic frequency.
- B. Migration changes allele frequency.
- C. There should not be selection.
- D. Non-random mating will reduce chances of evolution.
Explanation
Individuals with specific genotypes sometimes mate with one another more commonly than expected on a random basis. This is called non-random mating, causing the frequencies of particular genotypes to differ significantly from those predicted by the Hardy-Weinberg principle. Hence, changes brought by non-random mating will increase the chances of evolution.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
