Consider a locus in which the fitness of AA and Aa genotypes are greater than the fitness of aa genotype. In addition, this locus experiences forward mutation from the A allele to a allele. At this locus, the A allele:

a.
will always go to fixation.

b.
will always be lost.

c.
will never go to fixation.

d.
will never change.

e.
None of the above.

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).

just here for the other one bc they put up with u

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
