Answer:

There is a change in genetic frequency

Explanation:

Evolution may be defined as the change in the heritable and behavioral characteristics of an organisms over successive generations. Evolution may occur due to natural selection, mutation, recombination and gene flow.

Evolution can change the genotypic frequency of a population. If these changes are heritable they can pass down to the next generations and change the genotype frequency.

Thus, the correct answer is option (A).
