Answer:

Will never go to fixation.

Explanation:

Mutation is the sudden, heritable change in the genetic sequence of the organisms. The mutation might cause the particular disease in the organisms.

The  gene fitness leads to the increase in the gene frequency in the upcoming generations. The gene will fix in the population when their i no selection and no mutation. Since, the information given in the question states that mutation is acting, so the A allele will never fix in the population.

Thus, the answer is option (c).

Answer  and  Explanation:

Image result for How did the results prove the semiconservative model of DNA

The experiment done by Meselson and Stahl demonstrated that DNA replicated semi-conservatively, meaning that each strand in a DNA molecule serves as a template for synthesis of a new, complementary strand. Although Meselson and Stahl did their experiments in the bacterium E.
