Explain how genetic mutations may result in genetic and physical variations differences) within a population.

The correct answer is - Mutations produce different versions of genes.

Explanation:

Mutations are the changes in the gene or DNA of an organism that leads to the production of different version of genes and proteins. Mutations result in genetic variation or physical variation within the population as it introduces new alleles in the populations.

Mutations introduce or remove various versions of genes called alleles within a population and increases genetic variation. These changes in the genes are the source for new genetic variation. Genetic or physical variation does not occur without mutations.
