Question

Sometimes a mutation is beneficial to organisms fitness in can be passed onto the offspring. What is likely to happen to the mutation over many generations?
A. Any genetic variation will not persist because the mutation is a one time event.

B. There is a random chance of the mutation spreading to other individuals in the population.

C. The mutation will become more common in offspring and increase the genetic variability in the gene pool.

D. Genetic recombination is the only way that variations can be passed on so the mutation will die out.

Answer 1

Depends on the type of genetic mutation it is 
I believe that the answer could either be A or C. Sorry I cannot be of more help

Answer 2

Answer:

C. The mutation will become more common in offspring and increase the genetic variability in the gene pool.

Explanation:

The mutation which is beneficial to the organism's fitness occurs in the genetic cell of the individuals and after the fusion with the opposite gametic cell during fertilization it passes to the offsprings.  

So these offsprings reproduce the mutation will pass to some more offsprings and like this mutation will become more common in the population which will result in increasing the genetic variability of the in the gene pool. So the correct answer is C.
