Question

Sometimes a mutation is beneficial to an organism’s fitness and can be passed on to offspring. What is likely to happen to the mutation over many generations?

Any genetic variation will not persist because the mutation is a one-time event.
There is a random chance of the mutation spreading to other individuals in the population.
The mutation will become more common in offspring and increase the genetic variability in the gene pool.
Genetic recombination is the only way that variations can be passed on, so the mutation will die out.

Answer 1

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

Step-by-step explanation:

Mutations get transferred from parent to progeny by means of crossing over phase of meiosis only. Thus only germline mutations are inherited and not somatic ones.

Organisms with favourable mutations have more chances of survival. Thus, based on probability, Offspring's of such organisms will tend to show the mutation more than others

Answer 2

The mutation will occur often in offspring and leads to development of genetic variability in the gene pool.

Answer: C

Explanation:

Mutation refers to the process which causes disturbances in the normal DNA pattern.

When such phenomenon occurs over many generations, it will become a common process in offspring and increase the chance of difference in variability in the genetic makeup as well as the gene pool.

It is because, the first stage of mutation appears tedious to the organism.

As it gets transferred from one generation to another generation, the species due to its capability identifies certain ways and exhibit genetic variability due to the mutation.

By this way the mutation will become more common in offspring as their parent have mated in the presence of mutation.
