genetic variation

Genetic variation is brought about by mutation, genetic recombination, and gene flow in a population. Therefore, option (C) is correct.
The differences in DNA sequences that exist between individuals within the same group are referred to as genetic variation. Both germ cells, which include sperm and eggs, and somatic cells, which include all other types of cells, are subject to variation.
One source of genetic variation is mutations, which can be defined as any alteration in the sequence of genes found in DNA. Gene flow, which can be defined as the movement of genes across various groups of organisms, is still another source. The final cause of genetic diversity is sexual reproduction, which results in the formation of new gene combinations and can be a consequence of sexual reproduction.
