Quizplus · Accepted Answer

The process of cell division that forms the gametes (sperm and egg cells) with half the normal number of chromosomes (23 instead of 46) is called meiosis. Meiosis involves two rounds of cell division, resulting in four cells with unique combinations of chromosomes due to a process called crossing over. Mutations can occur during DNA replication but are not directly related to the formation of gametes. Mitosis results in two identical cells and does not involve the formation of gametes.
