Eukaryotic cells may divide through the process of mitosis or meiosis. In humans, mitosis generates new cells for growth and repair; meiosis produces sex cells (gametes) known as sperm and eggs.\Though mutations are ultimate source of the genetic variability, both the meiosis and the sexual reproduction may contribute to new genetic combinations within the offspring.
Question: Explain how do both the meiosis and the sexual reproduction (fertilization) generate the offspring which differ genetically from the parents?
