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