The frequency of allele if it is evolutionarily successful is:
Correct answer: A. Increased
- A. Increased
- B. Decreased
- C. No change
- D. None of these
Explanation
If an allele is evolutionary successful, its frequency is increased. The alleles, that are favorable for the survival and adaptation of an organism in its environment, are selected by natural selection and their frequency is increased in the next generations.

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.
