Meiosis – Via either crossing over (prophase I) or independent assortment (metaphase I) WebNov 26, 2024 · In general, mutation is the primary source of genetic variation, which is the raw material for evolution through natural selection. A change in the DNA sequence is a mutation. Often these differences in gene sequences may be beneficial for an organism. By modifying genes and alleles in a population, mutations result in genetic variation.
