Correct answer: A. Increased
- A. Increased
- B. Decreased
- C. No change
- D. None of these options are correct
Explanation
Allele frequency, also known as gene frequency, refers to how common an allele is in a population. If an allele leads to a successful and helpful trait in evolution, its frequency will eventually increase to benefit the species.

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.
