If we consider the Hardy-Weinberg law, then which of the following is incorrect in its sense?

Correct answer: D. Non-random mating will reduce the chances of evolution

  • A. Mutations cause changes in genetic frequency
  • B. Migration changes allele frequency
  • C. There should not be a selection
  • D. Non-random mating will reduce the chances of evolution

Explanation

The correct answer is Option D: Non-random mating will reduce the chances of evolution. This statement contradicts the Hardy-Weinberg principle because non-random mating can significantly alter genotype frequencies and therefore increase the likelihood of evolutionary changes. In contrast, options A, B, and C describe factors that correctly affect allele frequencies and disrupt the Hardy-Weinberg equilibrium: mutations introduce new alleles, migration alters allele frequencies through the movement of individuals, and selection changes allele frequencies by favouring certain traits.

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.
