Which of the following is NOT a source of genetic variation?
nikklg [1K]

Answer:

The correct answer is option d) age of either or both parents.

Explanation:

Genetic variation is the difference in nucleotide sequences between individuals organisms within a particular population. Variation can occur either in germ cells that are sperm and egg or in somatic cells or in both.
