Question

genetic variation accounts for differences between individuals in a population. which of these is not a cause of genetic variation?
a mutation
b random fertilization
c asexual reproduction
d crossing over or recombination

(image showing cell division and dna replication with labeled parts, and multiple - choice options a - d related to genetic variation causes)

Explanation:

To determine which is NOT a cause of genetic variation, we analyze each option:

• Mutation: Changes DNA, introducing new alleles (causes variation).
• Random fertilization: Combines random gametes, increasing variation.
• Asexual reproduction: Produces offspring genetically identical to the parent (no variation introduced).
• Crossing over/recombination: Shuffles genetic material during meiosis (causes variation).

Asexual reproduction does not create genetic differences between individuals in a population.

Answer:

C. asexual reproduction
