Genetic variation is defined as the change in the genetic sequence of an organism of species. The genetic variation can be due to natural selection or mutation.
The correct answer is:
Option C. DNA polymerase errors during replication
Genetic variation can be caused by mutation. The mutation is the alteration of a genetic sequence, by inserting or deleting the nucleotide. The mutation can lead to the entry of a new allele in a population.
The chances of genetic variation in a population are most likely due to errors made by DNA polymerase during replication.
DNA replication is an essential process in which genetic material from the parent is transmitted to the daughter cell. However, the mutation or errors caused during the replication will lead to genetic variation.
Therefore, Option C is correct.
