👉 Heterofertilization is a genetic mutation that causes two genetically identical cells to produce two different types of gametes, which are sperm and eggs. This results in the production of a single type of cell with unique characteristics, such as a chromosome set or specific protein expression patterns. Heterofertilization can occur during sexual reproduction, but it also occurs in somatic cells (eggs, sperm) where genetic material is not exchanged between two different cells.
