Random fertilization adds to genetic variation primarily through **B. random fusion of genetically unique gametes**.
During sexual reproduction, each parent produces gametes (sperm and eggs) that contain a unique combination of genes due to processes like meiosis and independent assortment. When fertilization occurs, the fusion of these unique gametes results in offspring with a new genetic combination, contributing to the overall genetic diversity of the population.
Options A and C relate to other genetic processes (like independent assortment and crossing over, respectively) but specifically pertain to the events leading to gamete formation rather than the process of fertilization itself.
