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.
I would say 2 but i might be wrong
