उत्तर
Genetic drift
Explanation:
Genetic variation within an individual organism comes from processes that generate changes in genetic material, such as recombination, mutation, and crossing-over, all of which alter or reshuffle genes during reproduction. Genetic drift, however, is a random change in allele frequencies that occurs in populations, not within an individual organism’s genome.
